摘要: 针对非匹配扰动影响下的直线感应电机速度跟踪问题进行研究,基于扩张扰动观测器设计了一种新型积分滑模控制器,使电机在非匹配扰动下具有良好的响应特性。针对带有边缘效应的直线感应电机模型,为其中的非匹配扰动分别设计了扩张扰动观测器,对扰动导数的观测值进行滤波处理,基于扰动量及其导数的观测值设计了新型积分滑模控制器(EDO-NSMC)。仿真研究表明所设计的控制器具有良好的响应特性和鲁棒性,并且减轻了传统滑模控制器的抖振效应。

Abstract: The speed-tracking problem of linear induction motors under the influence of unmatched disturbances is studied. Based on the extended disturbance observers, the novel sliding mode controllers are designed to make the motor have effective response characteristics under unmatched disturbances. The extended disturbance observersis designed for the unmatched disturbances in the linear induction motor model with edge effects. The observations of the disturbance derivatives are filtered. The novel sliding mode controllers are designed based on the observations of the disturbances and their derivatives. The simulations results show that the designed controller has effective response characteristics and robustness. In addition, it reduces the chattering effect in traditional sliding mode controllers.

Key words: linear induction motor, edge effect, unmatched disturbance, extended disturbance observer, sliding mode control
