Abstract

This paper addresses the rotor speed estimation problem of induction machine drives. A scheme based on discrete-time formulation of the Sliding Mode Observer is proposed and analyzed. The method is suitable to close-loop sensorless control of induction machines. The stability analysis and parameter convergence of the proposed method is presented. Simulation and experimental results based on DSP platform (TMS320F2812) demonstrate the good performance of the proposed sensorless control scheme.
