经济转型升级、供给侧改革背景下我国货币金融环境研究

第40届中国控制会议

作者： weichuan xu xuan Chang Hesheng Zhang Xiaojin Zhu School of Mechatronic Engineering and Automation Shanghai University

In this paper, the balance control of a single inverted pendulum is studied. Firstly, the mathematical model of the inverted pendulum system is established by using Newtonian mechanics method, and two parallel fuzzy controllers are used to control the position of the car and the angle of the pole respectively, so that the inverted pendulum system can reach a balanced position as soon as possible. Then the control effect of the controller is verified by SIUMLINK simulation and compared with the PID controller. Finally,the 3 D model was established by V-Realm Builder and co-simulated with SIMULINK. The results show that the fuzzy controller designed in this paper has a good control effect on the inverted pendulum.

Micro-vibration Active Control based on FXAPA algorithm

第40届中国控制会议

作者： xuan Chang weichuan xu Muyao Shao Zhiyuan Gao Xiaojin Zhu School of Mechatronic Engineering and Automation Shanghai University

This paper proposed a filter-x affine projection（FXAPA） algorithm based on affine projection（APA） algorithm, by reusing delayed input signals to improve the convergence speed of the algorithm effectively. Considering the dynamics and drive characteristics of the vibration active control system, hysteresis model was established using Bouc-Wen model. Simulation of the three-degree-of-freedom piezoelectric micro-positioning platform and the simulation verification of the control method were realized. The simulation and experiment results verified that the proposed vibration control algorithm of this paper has good control effect in micro-vibration active control.
