摘　　要：提出了一种考虑输入电压波动的永磁同步电动机指令滤波神经网络自适应离散容错控制方法。首先,建立考虑输入电压波动的永磁同步电动机系统离散模型;其次,采用指令滤波器逼近非线性函数,处理反步法中的“因果矛盾”和“计算复杂性”等问题,结合神经网络自适应技术针对输入电压波动问题进行控制器设计;最后,通过李雅普诺夫稳定性理论验证了闭环系统半全局一致最终有界。实验结果证明,所设计的容错控制器能够积极降低电动机电压波动对系统稳定运行产生的影响,具有良好的鲁棒性。An adaptive discrete fault-tolerant control method of permanent magnet synchronous motor(PMSM)with command filter neural network considering input voltage fluctuation is proposed.Firstly,a discrete model of PMSM system is established considering the problem of motor input voltage fluctuation;secondly,the novel command filtering method is used to solve the problems of“causal contradiction”and“computational complexity”in the backstepping method,and the fault-tolerant controller is designed by neural network adaptive method to overcome the problem of input voltage fluctuation;it is proved that the closed-loop system is semi-global uniformly and ultimately bounded by Lyapunov stability theory.Finally,experimental results show that the designed fault-tolerant controller can effectively overcome the influence of motor voltage fluctuation on the system,and has good robustness.
