SLIDING MODE APPLICATION IN POSITOIN CONTROL OF AN INDUCTION MACHINE

In this paper, we propose a sliding mode technique to control the position of the field-oriented induction machine. Our aim is to make the position control robust to parameter variations. The variation of motor parameters during operation degrades the performances of the controllers. The use of the nonlinear sliding mode method provides best performances for motor operation and the robustness of the control law despite the external/internal perturbations. Simulation results are given to highlight the performances of the proposed control technique under load disturbances and parameter uncertainties.
