Abstract

This paper addresses a novel strategy for speed estimation based on feedback linearization control for three-phase induction motors. A sensorless scheme based on discrete time formulation of the Sliding Mode Observer is proposed and stability analysis through Lyapunov method is presented. Experimental results based on DSP platform (TMS320F2812) demonstrate the good performance of the proposed sensorless control scheme.
