Indirect Vector Control of Induction Motor using Adaptive Sliding Mode Controller

Abstract

This paper presents an implementation of Adaptive Sliding Mode Controller (ASMC) based robust speed control strategy for Indirect Vector Control (IVC) three phase Induction Motor (IM) drive. The software platform for modelling of IM in the synchronous rotating frame of reference for IVC is Matlab/Simulink. The primary focus of the proposed controller is to accomplish robustness for electrical faults perturbations, load disturbances, speed variation, and parameter uncertainties. The performance of the proposed control technique is compared with that of the conventionally tuned PI control scheme. The Simulation results of the ASMC guarantee effectiveness and robustness regarding overshoot, undershoot, rise time, fall time, and chattering for different operating conditions compared to the traditional PI control scheme.
