FUZZY SLIDING MODE APPLICATION FOR INDUCTION MACHINE POSITION CONTROL

The use of the sliding mode control can give good transient performances and system robustness. However, the presence of the chattering may introduce problems to the system. In order to utilize the advantage of both fuzzy and sliding mode controls, a fuzzy sliding mode controller (FSMC) is proposed for position control. In this paper, we propose a fuzzy sliding mode controller to control the position of the field-oriented induction machine fed by voltage source inverter. Our aim is to make the position control robust to parameter variations. Simulation results are given to highlight the performances of the proposed control technique under load disturbances and parameter uncertainties.
