解耦自适应反步法永磁直线同步电机混沌控制
Chaos control of permanent magnet linear synchronous machine based on decoupling adaptive back-stepping method
摘要
Abstract
Aiming at the chaos dynamic behaviors existing in operation process of permanent magnet linear synchronous machine,the chaos model of machine was established in this paper.The largest Lyapunov exponents of the chaos model were calculated by programming with arbitrary parameter.Based on analyzing the chaotic dynamic characteristics of PMLSM,the state feedback decoupling controller was constructed and the order of the chaos system was reduced.The back-stepping chaos controller was designed with state feedback decoupling model.According to the uncertain parameters of PMLSM system,an adaptive back-stepping method was proposed with decoupling model.The virtual control quantity was structured and the control law was designed to track and forecast the system parameters in real time.The stability analysis was carried out by constructing the Lyapunov equation to make the state of the system converge to zero quickly and stably.The simulation results show that the PMLSM chaotic system could quickly restore to a stable operation status with the proposed decoupling adaptive back-stepping method with strong robustness,fast response and high control accuracy.关键词
