A Flux Observer of Voltage-Current Model Based on PI Regulator

Abstract:

This paper proposes a flux observer of voltage-current model based on PI regulator .Flux estimator value of current model at low speed is convergent gradually, so we adopt the current model. On the basis of traditional voltage model, we adopt improved model which substitute pure integral part with first-order inertia part and a compensation part, and it can solve DC drift and initial value with this method. Two models can be switched smoothly without concussion by setting appropriate PI parameter. The performance of the model is investigated and verified experimentally.
