感应电动机解耦变结构控制系统抖振抑制和消除的研究

THE STUDY OF QUIVER ELIMINATION AND RESTRAINT FOR THE DECOUPLING-VARIABLE STRUCTURE CONTROL SYSTEM IN INDUCTION MOTOR

本文在设计出一种新型的交流电动机控制系统──解耦变结构控制系统的基础上［１］，对其中滑模变结构带来抖振问题进行了研究，通过分析系统抖振产生的原因，提出了抖振抑制和消除的方法，并对各种方法进行比较，选择了最适合本系统的小区间ＰＩ控制法．文中还给出了仿真曲线和分析．

In this paper,on the basis of a new type control system in induction motor-decoupling variable structure control system[1].The quiver is the key problem in the sliding mode variable structure Control system.This problem is specially studied.The causes which lead to quiver are analysed.The methods of quiver elimination and restraint is discussed and compared.Small range PI control method is selected as the suitable one in this system.Simulation curve and analysis is given in the paper.
