Abstract

The application of sliding mode control for improving the dynamic response of an induction motor based position servo system is presented. It provides attractive features such as fast response, good transient performance, and insensitivity to variations in plant parameters and external disturbances. However, one difficult problem, for which the sliding mode controlled servo system has not yet been popular, is chattering. This paper presents a new fuzzy sliding mode controller for a vector-controlled induction servomotor system to practically eliminate the chattering problem. Microcomputer based implementation of position servo system is employed. Both simulation and experimental results are presented. The performance of the drive is shown to be practically free from the chattering problem.<>
