| 1 | Relay Feedback Based Autotuning PID Control of Paper Basis Weight in Paper Making Process显示文摘The brief arts and crafts of the ordinary fourdrinier are introduced first.After the intractable points of paper basis weight (BW) control are analyzed,an autotuning PID/PI control algorithm based on relay feedback identification is proposed,which has such advantages as simple parameter adjustment,little dependence on process model,strong robustness and easiness to implementation.And it is very suitable for controlling such processes as BW loop with large time delay. | Tang Wei, Shi Songjiao & Wang MengxiaoDept. of Automation, Shanghai Jiaotong University, Shanghai 200030, P.

| 3 | Robust scheme of global parallel force/position regulators for robot manipulators under environment uncertainty显示文摘A simple robust scheme of parallel force/position control is proposed in this paper to deal with two prob- lems for non-planar constraint surface and nonlinear mechanical feature of environment: i) uncertainties in environment that are usually not available or difficult to be determined in most practical situations; ii) stability problem or/and integrator windup due to the integration of force error in the force dominance rule in parallel force/position control. It shows that this robust scheme is a good alternative for anti-windup. In the presence of environment uncertainties, global asymptotic stability of the resulting closed-loop system is guaranteed; it also shows robustness of the proposed controller to uncertain environment with complex characteristics. Finally, numerical simulation verifies results via contact task of a two rigid-links robot manipulator. | Chunqing HUANG Lisang LIU Xinggui WANG Songjiao SHI | 2007 | 控制理论与应用(英文版)2007,5,3: | 1 |

| 12 | Design of an Interpolated Controller for Stabilization of a Plant with Variable Operating Condition显示文摘In this paper, the stabilization of a linear SISO plant with variable operating condition is considered. The plant is described by a linear interpolation of proper stable co-prime factorizations of the transfer functions at two representative operating points. An interpolation of the stabilizing controllers for the representative models is designed to stabilize the plant, and the necessary and sufficient condition for the plant to be stabilized by the proposed controller is presented using the Nevanlinna-Pick interpolation theory [4, 5]. It is shown that the class of stabilization plants via the proposed controller in the paper is larger than that by the controller in reference [3]. An example is also given to illustrate this fact. | Yuan, Xiangyang Shi, Songjiao Ikeda, Masao | 2000 | Journal of Systems Engineering and Electronics2000,11,2: | 0 |
| 13 | Fixed-Order l_1-Control for Systems with Time-Delay显示文摘In this paper, fixed-order l1-control for systems with time-delay is studied, and sufficient conditions for solvability of state-feedback l1-control and dynamic output-feedback l1-control are obtained. This paper also gives the forms of solution to l1-controller. In the paper, the problem is not cast into infinite dimensional constrained convex optimal problem, but an upper bound of l1-norm is optimized. Although the l1-control is sub-optimal, the analysis and design are simple. The result of the paper improves and develops the l1-control method. | Liu Yungang, Shi Songjiao & Qin Bin (Dept. of Automation, Shanghai Jiaotong University, 200030, P. R.

| 14 | Deep Reinforcement Learning for IRS-Assisted UAV Covert Communications显示文摘Covert communications can hide the existence of a transmission from the transmitter to receiver.This paper considers an intelligent reflecting surface(IRS)assisted unmanned aerial vehicle(UAV)covert communication system.It was inspired by the high-dimensional data processing and decisionmaking capabilities of the deep reinforcement learning(DRL)algorithm.In order to improve the covert communication performance,an UAV 3D trajectory and IRS phase optimization algorithm based on double deep Q network(TAP-DDQN)is proposed.The simulations show that TAP-DDQN can significantly improve the covert performance of the IRS-assisted UAV covert communication system,compared with benchmark solutions. | Songjiao Bi Langtao Hu Quanjin Liu Jianlan Wu Rui Yang Lei Wu | 2023 | China Communications2023,20,12: | 0 |
| 15 | A NOVEL H_∞/LTR SYNTHESIS METHOD显示文摘This paper focuses on the observer-based controller design problem and proposes a novel H∞/LTRsysthesis method in which the H∞ design technique is combined with the Loop Transfer Recovery (LTR) design methodology. The method involves two designing steps. First, an H∞ full state feedback controller is designed to satisfy the robust stability and performance specifications, which can be done independently of the recovery optimization. Subsequently, the properties of the H∞ state feedback can be reobtained by designing fullor reduced order observers. A case study is presented to illustrate the proposed method. | Weng Zhengxin Shi Songjiao(Depart. of Automatic Control, Shanghai Jiaotong University, Shanghai, 200030)Wang Guangxiong(Depart. of Control Engineering, Harbin Institute of Technology, Harbin, 150001) | 1996 | Journal of Shanghai Jiaotong university(Science)1996,1,2: | 0 |
| 16 | H_∞ ROBUST PERFORMANCE DESIGN FOR UNCERTAIN SYSTEMS显示文摘This paper considers the robust per formance design problem of the linear systems with both unmodelled dynamics and real parametric uncertainties. We suggest for the first time that the problem can besolved by the H∞ mixed sensitivity method. The main idea is as follows: Firstly, the original problem istransformed into the robust per formance design problem for a pure parameter uncertain system. Then, theresulting problem is reduced to a standard H∞ control problem which can be solved by the H∞ state feedbacksynthesis method or Doyle’s 'DGKF' algorithm. | Weng Zhengxin Shi Songjiao(Dept. of Automatic Control, Shanghai Jiaotong University, Shanghai, 200030)Wang Guangxiong(Dept. of Control Engineering, Harbin Institute of Technology, Harbin, 150001) | 1996 | Journal of Shanghai Jiaotong university(Science)1996,1,2: | 0 |
