Design of Robust Backstepping Controller for Permenent Magnet Linear Synchronous Motor Servo Systems
摘要
Abstract
A robust backstepping controller for permanent magnet linear synchronous motor (PMLSM) servo systems to meet the requirements of strong robust and high precision was presented.To solve the problems of lowaccuracy,difficult parameters tuning and weak robust,an adaptive controller and a backstepping one were combined.The introduction of adaptive mechanism released the priori knowledge of upper bounds on disturbance and overcomed the chattering problem of the control law.Meanwhile,the characteristics and the bad impacts of high-frequency noise in feedback control systems were analyzed,and a low pass filter was applied to suppress the high-frequency noise.Finally,the effectiveness of the proposed controller and the suppression of the high-frequency noise were verified in the experimental platform,made by Googol company.This paper could provide references to the practicality of advanced control theory.关键词
