A New PI -Fuzzy Sliding Mode Controller .Application to the Dual Star Induction Machine (DSIM)

Abstract

This work investigates a simple design of the new PI-Fuzzy Sliding Mode Controller (FSMC) for speed regulation of an indirect field-oriented dual star induction motor (DSIM). The fuzzy controller is driven by the error of the speed, and it change. The sliding mode controller is designed based on a plant model. The influence of different combinations of the FLC and SMC on the performance control is investigated and illustrated by some simulation results at different dynamic operating conditions such as sudden change in command speed, step change in load torque and some key parameters deviation. Finally the proposed controller is insensitive to parameter variations and load disturbances.
