交流伺服系统的高精度滑模控制

High-accuracy Sliding Mode Control for An AC Servo System

本文针对滑差频率型矢量控制的交流伺服系统，设计了一种新颖的滑模控制器；采用插入积分环节的方法有效地削弱了滑模控制的抖动。理论分析、仿真与实验结果表明由该滑模控制器和积分环节组成的控制策略能使系统同时具备良好的鲁棒性和快速性、无超调，以及极高的定位精度等优点。其控制策略的实现非常容易，从而为高性能交流伺服系统的控制提供了一种行之有效的方法。

This paper disigns a novel sliding mode controller for an indirect vector control a c servo system and effectively decreases chattering by inserting an integral loop. Theory analysis and simulation and experimental results show that the control strategy composed of the sliding mode controller and integral loop enables the system to be of good robustness and fastness and no-overshoot and very high accuracy. It is easy bo be applied. It provides an effective method for the control of high-performance a c servo system.
