摘要

提出了一种基于变结构控制和动态递归模糊小波网络的永磁同步电机鲁棒位置控制器。基于VSC方法的闭环系统可以实现对不确定性具有不变性的系统动力学。然而，基于已知不确定性边界假设的滑动控制器在控制系统中经常引起抖振现象。采用自适应学习率的DRFWN辨识方法，对系统参数变化和外部负载扰动引起的永磁同步电机不确定界进行了辨识。在实验和仿真两种不同条件下，对所提出的驱动器的性能进行了研究

A Fuzzy-Wavelet-Network-Based Position Control for PMSM

A robust position controller with variable structure control (VSC) and dynamic recurrent fuzzy wavelet network (DRFWN) technique for permanent magnet synchronous motor (PMSM) is presented in this paper. Based on the VSC method, the closed-loop system can system dynamics with an invariance property to uncertainties. However, the sliding controller based the assumption of known uncertainty bounds often cause the chattering phenomena in the control system. DRFWN identification with adaptive learning rates is implemented to evaluate the uncertainty bounds of PMSM which are caused by the variable of system parameters and the external load disturbance. The performance of the proposed drive is investigated both in experiment and simulation at different condition
