| 1 | A new adaptive mutative scale chaos optimization algorithm and its application显示文摘Based on results of chaos characteristics comparing one-dimensional iterative chaotic self-map x = sin(2/x) with infinite collapses within the finite region[-1,1] to some representative iterative chaotic maps with finite collapses (e.g., Logistic map, Tent map, and Chebyshev map), a new adaptive mutative scale chaos optimization algorithm (AMSCOA) is proposed by using the chaos model x = sin(2/x). In the optimization algorithm, in order to ensure its advantage of speed convergence and high precision in the seeking optimization process, some measures are taken: 1) the searching space of optimized variables is reduced continuously due to adaptive mutative scale method and the searching precision is enhanced accordingly; 2) the most circle time is regarded as its control guideline. The calculation examples about three testing functions reveal that the adaptive mutative scale chaos optimization algorithm has both high searching speed and precision. | Jiaqiang E Chunhua WANG Yaonan WANG Jinke GONG | 2008 | 控制理论与应用(英文版)2008，6，2： | 22 |

| 3 | Parameter selection of support vector machine for function approximation based on chaos optimization显示文摘The support vector machine (SVM) is a novel machine learning method, which has the ability to approximate nonlinear functions with arbitrary accuracy. Setting parameters well is very crucial for SVM learning results and generalization ability, and now there is no systematic, general method for parameter selection. In this article, the SVM parameter selection for function approximation is regarded as a compound optimization problem and a mutative scale chaos optimization algorithm is employed to search for optimal parameter values. The chaos optimization algorithm is an effective way for global optimal and the mutative scale chaos algorithm could improve the search e?ciency and accuracy. Several simulation examples show the sensitivity of the SVM parameters and demonstrate the superiority of this proposed method for nonlinear function approximation. | Yuan Xiaofang Wang Yaonan | 2008 | Journal of Systems Engineering and Electronics2008，19，1： | 18 |
| 4 | Design of PID controller with incomplete derivation based on differential evolution algorithm显示文摘To determine the optimal or near optimal parameters of PID controller with incomplete derivation, a novel design method based on differential evolution (DE) algorithm is presented. The controller is called DE-PID controller. To overcome the disadvantages of the integral performance criteria in the frequency domain such as IAE, ISE, and ITSE, a new performance criterion in the time domain is proposed. The optimization procedures employing the DE algorithm to search the optimal or near optimal PID controller parameters of a control system are demonstrated in detail. Three typical control systems are chosen to test and evaluate the adaptation and robustness of the proposed DE-PID controller. The simulation results show that the proposed approach has superior features of easy implementation, stable convergence characteristic, and good computational effciency. Compared with the ZN, GA, and ASA, the proposed design method is indeed more effcient and robust in improving the step response of a control system. | Wu Lianghong Wang Yaonan Zhou Shaowu Tan Wen | 2008 | Journal of Systems Engineering and Electronics2008，19，3： | 14 |
| 5 | Self-adapting control parameters modifieddifferential evolution for trajectoryplanning of manipulators显示文摘Control parameters of original differential evolution(DE)are kept fixed throughout the entire evolutionary process.However,it is not an easy task to properly set control parameters in DE for different optimization problems. According to the relative position of two different individual vectors selected to generate a difference vector in the searching place,a self-adapting strategy for the scale factor F of the difference vector is proposed.In terms of the convergence status of the target vector in the current population,a self-adapting crossover probability constant CR strategy is proposed. Therefore,good target vectors have a lower CR while worse target vectors have a large CR.At the same time,the mutation operator is modified to improve the convergence speed.The performance of these proposed approaches are studied with the use of some benchmark problems and applied to the trajectory planning of a three-joint redundant manipulator.Finally, the experiment results show that the proposed approaches can greatly improve robustness and convergence speed. | Lianghong WU Yaonan WANG Shaowu ZHOU | 2007 | 控制理论与应用(英文版)2007，5，4： | 12 |
| 6 | Determination of Electrical Conductivity of Cadaver Skeletal Muscle: A Promising Method for the Estimation of Late Postmortem Interval显示文摘The electrical conductivity(EC)of extracted muscle fluid has been extensively used to evaluate meat freshness and shelf life in the field of food sanitation for decades.The opposite of freshness is the corruption that increases with time.Based on the freshness/corruption principle,we investigated the relationship between long postmortem intervals(PMIs)and EC in cadaver skeletal muscle.EC values of extracted fluid from rat muscles were measured at different PMIs for 10 days.The results indicate that there was a significant correlation between PMI and EC,and the data fit well to the cubic polynomial regression equation y=‑0.01x3+0.264x2‑13.657x+1769.148(R2=0.925).In addition,the EC of different dilutions of these muscle extracts showed strict quadratic correlation(R2=1)with the dilution ratios,suggesting that EC can be measured with very small quantities of muscle sample.Our study suggests that determination of the EC of cadaver skeletal muscle extracts may be a useful method for estimating long PMIs. | Zhiyuan Xia Xiandun Zhai Beibei Liu Yaonan Mo | 2015 | Journal of Forensic Science and Medicine2015，1，1： | 8 |
| 7 | Spatio-temporal variation of hydrological drought under climate change during the period 1960–2013 in the Hexi Corridor, China显示文摘In recent years, climate change has been aggravated in many regions of the world. The Hexi Corridor is located in the semiarid climate zone of Northwest China, which is particularly affected by climate change. Climate change has led to the spatial and temporal variations of temperature and precipitation, which may result in hydrological drought and water shortage. Thus, it is necessary to explore and assess the drought characteristics of river systems in this area. The patterns of hydrological drought in the Hexi Corridor were identified using the streamflow drought index(SDI) and standardized precipitation index at 12-month timescale(SPI12) from 1960 to 2013. The evolution of drought was obtained by the Mann–Kendall test and wavelet transform method. The results showed that both the mean annual SDI and SPI12 series in the Hexi Corridor exhibited an increasing trend during the study period. According to the results of wavelet analysis, we divided the study period into two segments, i.e. before and after 1990. Before 1990, the occurrence of droughts showing decreased SDI and SPI12 was concentrated in the northern part of the corridor and shifted to the eastern part of the corridor after 1990. The probability of drought after 1990 in Shule River basin decreased while increased in Shiyang River basin. The wavelet analysis results showed that Shiyang River basin will be the first area to go through the next drought period. Additionally, the relationships between drought pattern and climate indices were analyzed. The enhanced westerly winds and increased precipitation and glacier runoff were the main reasons of wet trend in the Hexi Corridor. However, the uneven spatial variations of precipitation, temperature and glacier runoff led to the difference of hydrological drought variations between the Shule, Heihe and Shiyang River basins. | GAO Liming | 2016 | Journal of Arid Land2016，8，2： | 6 |
| 8 | New mixed broadcast scheduling approach using neural networks and graph coloring in wireless sensor network显示文摘Due to the mutual interference and sharing of wireless links in TDMA wireless sensor networks, confiicts will occur when data messages are transmitting between nodes. The broadcast scheduling problem (BSP) is aimed to schedule each node in different slot of fixed length frame at least once, and the objective of BSP is to seek for the optimal feasible solution, which has the shortest length of frame slots, as well as the maximum node transmission. A two-stage mixed algorithm based on a fuzzy Hopfield neural network is proposed to solve this BSP in wireless sensor network. In the first stage, a modified sequential vertex coloring algorithm is adopted to obtain a minimal TDMA frame length. In the second stage, the fuzzy Hopfield network is utilized to maximize the channel utilization ratio. Experimental results, obtained from the running on three benchmark graphs, show that the algorithm can achieve better performance with shorter frame length and higher channel utilizing ratio than other exiting BSP solutions. | Zhang Xizheng Wang Yaonan | 2009 | Journal of Systems Engineering and Electronics2009，20，1： | 5 |
| 9 | Large Chip Production Mechanism under the Extreme Load Cutting Conditions显示文摘There has existed a great deal of theory researches in term of chip production and chip breaking characteristics under conventional cutting and high speed cutting conditions,however,there isn't sufficient research on chip formation mechanism as well as its influence on cutting state regarding large workpieces under extreme load cutting.This paper presents a model of large saw-tooth chip through applying finite element simulation method,which gives a profound analysis about the characteristics of the extreme load cutting as well as morphology and removal of the large chip.In the meantime,a calculation formula that gives a quantitative description of the saw-tooth level regarding the large chip is established on the basis of cutting experiments on high temperature and high strength steel2.25Cr-lMo-0.25V.The cutting experiments are carried out by using the scanning electron microscope and super depth of field electron microscope to measure and calculate the large chip produced under different cutting parameters,which can verify the validity of the established model.The calculating results show that the large saw-toothed chip is produced under the squeezing action between workpiece and cutting tools.In the meanwhile,the chip develops a hardened layer where contacts the cutting tool and the saw-tooth of the chip tend to form in transverse direction.This research creates the theoretical model for large chip and performs the cutting experiments under the extreme load cutting condition,as well as analyzes the production mechanism of the large chip in the macro and micro conditions.Therefore,the proposed research could provide theoretical guidance and technical support in improving productivity and cutting technology research. | LIU Xianli HE Genghuang YAN Fugang CHENG Yaonan LIU Li | 2015 | Chinese Journal of Mechanical Engineering2015，28，2： | 5 |
| 10 | Improved differential evolution algorithm for resource-constrained project scheduling problem显示文摘An improved differential evolution(IDE)algorithm that adopts a novel mutation strategy to speed up the convergence rate is introduced to solve the resource-constrained project scheduling problem(RCPSP)with the objective of minimizing project duration Activities priorities for scheduling are represented by individual vectors and a senal scheme is utilized to transform the individual-represented priorities to a feasible schedule according to the precedence and resource constraints so as to be evaluated.To investigate the performance of the IDE-based approach for the RCPSP,it is compared against the meta-heuristic methods of hybrid genetic algorithm(HGA),particle swarm optimization(PSO) and several well selected heuristics.The results show that the proposed scheduling method is better than general heuristic rules and is able to obtain the same optimal result as the HGA and PSO approaches but more efficient than the two algorithms. | Lianghong Wu Yaonan Wang Shaowu Zhou | 2010 | Journal of Systems Engineering and Electronics2010，21，5： | 4 |

This control scheme integrates H-infinity disturbance attenuation design and recurrent neural network adaptive control technique into the dynamic surface control framework. Two recurrent neural networks are used to adaptively learn the uncertain functions in a flexible joint robot. Then, the effects of approximation error and filter error on the tracking performance are attenuated to a prescribed level by the embedded H-infinity controller, so that the desired H-infinity tracking performance can be achieved. Finally, simulation results verify the effectiveness of the proposed control scheme. | Zhiqiang MIAO Yaonan WANG | 2013 | 控制理论与应用(英文版)2013，11，2： | 4 |
| 12 | Robust adaptive tracking control of robotic systems with uncertainties显示文摘To deal with the uncertainty factors of robotic systems,a robust adaptive tracking controller is proposed. The knowledge of the uncertainty factors is assumed to be unidentified; the proposed controller can guarantee robustness to parametric and dynamics uncertainties and can also reject any bounded,immeasurable disturbances entering the sys-tem. The stability of the proposed controller is proven by the Lyapunov method. The proposed controller can easily be implemented and the stability of the closed system can be ensured; the tracking error and adaptation parameter error are uniformly ultimately bounded (UUB). Finally,some simulation examples are utilized to illustrate the control performance. | Yaonan WANG Jinzhu PENG Wei SUN Hongshan YU Hui ZHANG | 2008 | 控制理论与应用(英文版)2008，6，3： | 4 |
| 13 | Determining the Electrical Conductivity of Rat Cadaveric Liver,Spleen,and Kidney to Estimate Early Postmortem Interval显示文摘Previous research has found that electrical conductivity(EC),an important index to predict meat freshness and shelflife,is very promising for estimating the late postmortem interval(PMI).However,whether it has potential use in the early PMI has not been fully studied yet.To test this possibility in the present study,EC of three internal organs of rat liver,spleen,and kidney were determined within 24 postmortem hows,and then,EC changes at different PMIs were carefully analyzed.The overall results showed that EC of liver and spleen increased significantly with PMI while EC of kidney had minor changes during the same period.Specifically,significant linear positive correlations between EC of liver and spleen and PMI were found and the coefficients of their regression functions were R^(2)=0.98 and R^(2)=0.95,respectively.It can be concluded that determination of EC in certain internal organs such as liver and spleen may be a potential tool in the early PMI estimation.However,more researches on its influencing factors are needed to facilitate its final use in practice. | Zhe Zheng Xiandun Zhai Zhiyuan Xia Yaonan Mo | 2017 | Journal of Forensic Science and Medicine2017，3，3： | 3 |
| 14 | The Gaojiacun Mafic-Ultramafic Complex(Sichuan,SW China):Neoproterozoic Magmatic Activity at the Western Margin of the Yangtze Craton显示文摘The Neoproterozoic Gaojiacun intrusive complex(GIC)is composed of one big intrusion(ca.9 × 7.5 km)and numerous satellite intrusions,emplaced in the low-grade schists of the Neoproterozoic Yanbian Group.The main intrusion is concentrically zoned,with peridotite bodies + leucogabbroids in its core(inner zone)and the sequence:olivine hornblende gabbronorite-porphyric pyroxene hornblende gabbronorite(transitional zone)-pyroxene hornblende gabbronorite + hornblende gabbro + diorite(outer zone),towards the margins.The satellite intrusions are composed either of a single rock type(peridotite,gabbro,diorite or granite)or of different rock types(peridotite + diorite + granite).Upper crustal contamination is evidenced by the occurrence of numerous metamorphic enclaves,migmatites and mixed rocks in the outer zone of the main intrusion and in the satellite intrusions.Hornblende(often oikocrystic)is present in all mafic and ultramafic rocks.Cu-Ni(-PGE)deposits occur in several satellite intrusions,hosted in peridotite.The geochemical and mineralogical features of GIC support the presence of a subduction zone at the western edge of the Yangtze Craton.A feeder-related genesis of the satellite intrusions is inferred. | Marian MUNTEANU YAO Yong Allan H.

| 16 | Exploration and functionalization of M1-macrophage extracellular vesicles for effective accumulation in glioblastoma and strong synergistic therapeutic effects显示文摘Glioblastoma multiforme(GBM)is a highly aggressive brain tumor with an extremely low survival rate.New and effective approaches for treatment are therefore urgently needed.Here,we successfully developed M1-like macrophage-derived extracellular vesicles(M1EVs)that overcome multiple challenges via guidance from two macrophage-related observations in clinical specimens from GBM patients:enrichment of M2 macrophages in GBM;and origination of a majority of infiltrating macrophage from peripheral blood.To maximize the synergistic effect,we further functionalized the membranes of M1EVs with two hydrophobic agents(the chemical excitation source CPPO(C)and the photosensitizer Ce6(C))and loaded the hydrophilic hypoxiaactivated prodrug AQ4N(A)into the inner core of the M1EVs.After intravenous injection,the inherent nature of M1-derived extracellular vesicles CCA-M1EVs allowed for blood-brain barrier penetration,and modulated the immunosuppressive tumor microenvironment via M2-to-M1 polarization,which increased hydrogen peroxide(H_(2)O_(2))levels.Furthermore,the reaction between H_(2)O_(2) and CPPO produced chemical energy,which could be used for Ce6 activation to generate large amounts of reactive oxygen species to achieve chemiexcited photodynamic therapy(CDT).As this reaction consumed oxygen,the aggravation of tumor hypoxia also led to the conversion of non-toxic AQ4N into toxic AQ4 for chemotherapy.Therefore,CCA-M1EVs achieved synergistic immunomodulation,CDT,and hypoxia-activated chemotherapy in GBM to exert a potent therapeutic effect.Finally,we demonstrated the excellent effect of CCA-M1EVs against GBM in cell-derived xenograft and patient-derived xenograft models,underscoring the strong potential of our highly flexible M1EVs system to support multi-modal therapies for difficult-to-treat GBM. | Xiaojun Wang Hui Ding Zongyang Li Yaonan Peng Hui Tan Changlong Wang Guodong Huang Weiping Li Guanghui Ma Wei Wei | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 3 |

| 18 | Design of mixed H-two/H-infinity optimal control systems using multiobjective differential evolution algorithm显示文摘In this paper, the mixed H-two/H-infinity control synthesis problem is stated as a multiobjective opti-mization problem, with objectives of minimizing the H-two and H-infinity norms simultaneously. Instead of building a LMIs-based synthesis algorithm, a self-adaptive control parameter multiobjective differential evolution algorithm is developed directly in the controller parameters space. In the case of systems with polytopic uncertainties, the worst case norm computation is formulated as an implicit optimization problem, and the proposed self-adaptive differential evolution is employed to calculate the worst case H-two and H-infinity norms. The numerical examples illustrate the power and validity of the proposed approach for the mixed H-two/H-infinity control multiobjective optimal design. | Lianghong WU Yaonan WANG Shaowu ZHOU Xiaofang YUAN | 2013 | 控制理论与应用(英文版)2013，11，3： | 2 |
| 19 | Adaptive-backstepping force/motion control for mobile-manipulator robot based on fuzzy CMAC neural networks显示文摘In this paper, an adaptive backstepping fuzzy cerebellar-model-articulation-control neural-networks control(ABFCNC) system for motion/force control of the mobile-manipulator robot(MMR) is proposed. By applying the ABFCNC in the tracking-position controller, the unknown dynamics and parameter variation problems of the MMR control system are relaxed. In addition, an adaptive robust compensator is proposed to eliminate uncertainties that consist of approximation errors, uncertain disturbances.Based on the tracking position-ABFCNC design, an adaptive robust control strategy is also developed for the nonholonomicconstraint force of the MMR. The design of adaptive-online learning algorithms is obtained by using the Lyapunov stability theorem. Therefore, the proposed method proves that it not only can guarantee the stability and robustness but also the tracking performances of the MMR control system. The effectiveness and robustness of the proposed control system are verified by comparative simulation results. | Thang-Long MAI Yaonan WANG | 2014 | Control Theory and Technology2014，12，4： | 2 |
| 20 | Modeling and Control of a V2G Charging Station Based on Synchronverter Technology显示文摘This paper proposes an idea for modeling and con-trol of a V2G charging station(CS)for electric vehicles(EVs)by using synchronverter technology.First,the architecture of the CS is introduced.Then,a T-S fuzzy controller is designed to decide the reference real power of the synchronverter by considering the grid frequency.Due to the inner frequency-and voltage-drooping mechanisms of the synchronverter,the input and output real and reactive power of the CS will be automatically adjusted on the basis of the reference value according to the degree of deviation from the nominal value of the grid frequency and voltage.To ensure the safety of this operation,an adaptive frequency droop coefficient mechanism is designed to adapt the change of the total energy storage of a CS unit by changing the slope of the P-f control characteristic of the synchronverter.The performance of the CS with the proposed control strategy is investigated with EVs of different battery states,different users’sets and under different grid status.Simulation results demonstrate that the proposed strategy can not only effectively perform controlled charging/discharging of each single electric vehicle inside the CS,but also improve the performance of the electricity grid in terms of efficiency,stability and reliability. | Dongqi Liu Qingchang Zhong Yaonan Wang Guorong Liu | 2018 | CSEE Journal of Power and Energy Systems2018，4，3： | 2 |
