Abstract

A compensated voltage model is proposed in this paper, which consists of a second order band pass filter and its compensator. Based on this compensated voltage model, a new flux estimator is constructed. To solve this multiple equilibrium states problem, a method to improve the flux estimator is proposed and the different kinds of induction motor flux observer control technology are studied. The traditional model reference adaptive speed estimation method is modified and using the band pass filter compensated voltage model proposed in this paper as the reference model. The precision of speed estimation is improved. On the basis of this modified model reference adaptive speed estimation method, a speed sensorless induction machine vector control strategy is proposed and then validated through simulation.
