A discrete model of induction motors for real-time control applications

Abstract

The real-time digital control of induction motors and AC servomotor drives often involves estimation, identification, and adaptive control algorithms. An efficient and numerically stable discrete model of the induction motor is required to implement these algorithms in real time. A predictor-corrector discrete model of induction motors is developed here for real-time model is analyzed by a discrete root locus technique. The digital simulation of the model is presented and compared with a rigorous solution, and satisfactory results are obtained.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
