Abstract :
This paper presents a differential algebraic approach of speed/position estimation for PMSM drive. The dynamic of the position is a function of the voltages, currents and their derivatives. In contrast to the other estimators like the Extended Kalman Filter (EKF) that is complex and computationally expensive, the differential algebraic estimator is simple with a one-dimension model. Simulations and experimental results show the effectiveness of the method.
