摘要
对高精度永磁同步电动机伺服系统的转速环控制策略进行综述。首先介绍两种常用的解耦线性化方法,并给出不同解耦方法下控制系统的结构图。然后,重点总结转速环控制器的设计,其中的主要问题是如何抑制系统参数不确定或时变以及外部扰动对转速控制的影响。许多现代控制方法被应用到转速控制器的设计中,包括自适应控制、自适应逆推方法、变结构控制和鲁棒控制,着重对这些研究结果进行总结,并予以分析和比较,最后指出今后需要开展研究的方向。
This paper presents a review of the speed control strategies for PMSM servo systems. Firstly, two common decoupling linearization methods are introduced, and the structure of the systems designed by different methods are given. Then the designing of the speed controller is discussed with main concern about the problem of suppressing the influence of uncertainty or variation of system parameters and disturbance. Several modern control methods applied to PMSM systems are reviewed including self-tuning control, selftuning backstepping methods, variable structure control and robust control. Analysis and comparison are made while prospects of future development are given.
