The design and implementation of an induction motor driver using a sliding mode model following control with sinusoidal command input

Abstract

A Sliding mode Model Following Control or SMFC strategy for an induction motor driver is presented. A procedure is proposed for choosing the control function so that it guarantee the existence of a sliding mode. Moreover, the chattering in the control signal is suppressed by replacing the sign function in the control function with a continuous function. The SMFC approach has been implemented on a microcomputer and applied to a position control of an induction motor. Experimental results illustrate that SMFC gives a significant improvement on the tracking performances and robust to plant parameter variations and disturbances.
