| 1 | Operator-Based Robust Nonlinear Control for SISO and MIMO Nonlinear Systems With PI Hysteresis显示文摘In this paper, operator based robust nonlinear control for single-input single-output(SISO) and multi-input multi-output(MIMO) nonlinear uncertain systems preceded by generalized Prandtl-Ishlinskii(PI) hysteresis is considered respectively. In detail, by using operator based robust right coprime factorization approach, the control system design structures including feedforward and feedback controllers for both SISO and MIMO nonlinear uncertain systems are given, respectively.In which, the controller design includes the information of PI hysteresis and its inverse, and some sufficient conditions for the controllers in both SISO and MIMO systems should be satisfied are also derived respectively. Based on the proposed conditions, influence from hysteresis is rejected, the systems are robustly stable and output tracking performance can be realized.Finally, the effectiveness of the proposed method is confirmed by numerical simulations. | Shuhui Bi Lei Wang Shengjun Wen Mingcong Deng | 2018 | IEEE/CAA Journal of Automatica Sinica2018，5，2： | 3 |
| 2 | Operator-Based Robust Nonlinear Free Vibration Control of a Flexible Plate With Unknown Input Nonlinearity显示文摘In this paper,a robust nonlinear free vibration control design using an operator based robust right coprime factorization approach is considered for a flexible plate with unknown input nonlinearity.With considering the effect of unknown input nonlinearity from the piezoelectric actuator,operator based controllers are designed to guarantee the robust stability of the nonlinear free vibration control system.Simultaneously,for ensuring the desired tracking performance and reducing the effect of unknown input nonlinearity,operator based tracking compensator and estimation structure are given,respectively.Finally,both simulation and experimental results are shown to verify the effectiveness of the proposed control scheme. | Guang Jin Mingcong Deng | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，2： | 2 |

| 4 | Decentralized PD Control for Non-uniform Motion of a Hamiltonian Hybrid System显示文摘In this paper,a decentralized proportional-derivative(PD)controller design for non-uniform motion of a Hamiltonian hybrid system is considered.A Hamiltonian hybrid system with the capability of producing a non-uniform motion is developed. The structural properties of the system are investigated by means of the theory of Harniltonian systems.A relationship between the parameters of the system and the parameters of the proposed decentralized PD controller is shown to ensure local stability and tracking performance.Simulation results are included to show the obtained non-uniform motion. | Mingcong Deng Hongnian Yu Akira Inoue | 2008 | International Journal of Automation and computing2008，5，2： | 1 |
| 5 | Using a pressure controlled vortex design method to control secondary flow losses in a turbine stage显示文摘A turbine design method based on pressure controlled vortex design(PCVD) is presented to design a small-size turbine stage.Contrary to the conventional controlled vortex design(CVD)method,the main objective of PCVD is to control the axial velocity and radial pressure in the stator–rotor gap.Through controlling axial velocity,the PCVD establishes a direct tie to meridional stream surface.Thus stream surface variation is induced,resulting in a large secondary flow vortex covering the full blade passage in the respective stator and rotor.This secondary flow vortex could be dedicated to control the secondary flow mitigation and migration.Through radial pressure,the PCVD is also associated with the macroscopic driving force of fluid motion.So the better beneft of CVD can be achieved.The core concept behind PCVD is to mainly control the spanwise pressure gradient by altering profle loading at various spanwise locations.Therefore not only the local profle lift is affected,but also the resulting throat widths,stage reaction degree,and massflow rate are altered or redistributed respectively.With the PCVD method,the global stage effciency is increased successfully while the mass flow rate keeps constant.Additionally there is no endwall shape optimization,stacking optimization,or pitch/chord variations,concentrating solely on varying blade profle deflections and stagger. | Deng Qingfeng Zheng Qun Yue Guoqiang Zhang Hai Luo Mingcong | 2013 | Chinese Journal of Aeronautics2013，26，5： | 0 |
