Switching Gain Adaptive Current Control Strategy for Brushless DC Motor
摘要
Abstract
In order to improve the drive control performance of brushless DC motor,a novel switching gain adaptive current control strategy was designed. The new controller consisted of two modules:the continuous control module and the switching control module. The former combined model reference adaptive control to cope with parameter uncertainties,and the latter combined sliding mode control to eliminate interference caused by approximate error and unstructured uncertainties. The switching gain adaptive method used in the new control strategy was based on unknown interference estimation,and current high frequency noise caused by chattering was eliminated. Finally,the effect of the new control method is verified by experiments.关键词
