Sensorless Speed Integral Sliding Mode Control with Adaptive Sliding Mode Observer Design of Induction Motor

Abstract

Sliding-mode control has such advantages as robustness, simple algorithm and good dynamic performance, in this paper we introduce the integral sliding mode control for induction motor based to proposed an integral term in switching surface to have a robust control to parametric and perturbation errors. An accurate knowledge of the rotor speed, rotor flux and adaptatin of resistive parameters are the keys factors in obtaining a high-performance and high-efficiency induction-motor drive, for that,a sliding mode observer design is presented. Simulation results are included to illustrate the performance of sensorless induction motors with flux observer and good results are obtained.
