解耦变结构交流速度控制系统的研究

The Study of the AC Speed Control System with Decoupling-Variable Structure Control

本文提出了一种新型的AC速度控制系统——解耦变结构控制系统。它利用解耦原理简化感应电动机的数学模型,然后采用变结构控制原理克服转子电阻随温度变化带来的不良影响,保证了系统的动态和静态性能。文中推导出解耦变结构速度控制系统的数学模型、滑模控制器结构,并给出仿真结果。

A new AC speed control system-decoupling variable structure control system is proposed in this paper. The decoupling control theory is applied to the induction motor in order to simplify the mathematical model of the induction motor, and the variable structure control theory may surmount the defective result of the variation of the rotor risistor with temperature. A dynamic and static performance can be guaranteed. In this paper, the mathematical model of decoupling variable structure control system, structure of sliding mode controller and simulation results are given.
