Abstract

The application of sliding mode control for improving the dynamic response of an induction motor based speed control system is presented. It provides attractive features such as fast response, good transient performance, insensitivity to variations in plant parameters and external disturbance. However, one difficult problem for which the popular is due to chattering. This paper presents a new fuzzy-sliding mode controller for a senserless vector controlled induction motor servo system to practically eliminate the chattering problem for traction applications. DSP based implementation of speed control system is employed. Experimental results are presented using propulsion system simulator. The performance of the drive is shown to be practically free from chattering problem.
