高性能交流伺服系统的一种新型控制策略

A Novel Control Strategy of High-performance AC Servo Systems

本文从滑模变结构理论出发,针对交流伺服系统,提出一种新型控制策略。理论分析、仿真与实验结果表明该控制策略能使交流伺服系统同时具备良好的鲁棒性和快速性,定位无超调,定位精度和跟踪精度高等优点,并且改变了传统的三环串级模式,简化了系统结构。其控制策略易于数字实现,为高性能交流伺服系统的控制提供了一种简单有效的实用方法。

This paper presents a novel control strategy for AC servo systems hased on sliding mode variable structure theory. Theory analysis and simulation and experimental results show that it can make AC servo systems have good robustness, fast response, non-overshoot and high accuracy. It changes traditional three loops cascade mode and makes the structure of system simple. It provides a simple and effective and useful method for the control of high-performance,AC servo system.
