This paper describes a method to diagnose current sensor fault in a Permanent Magnet Synchronous Machine (PMSM) drive for automotive applications. The method is based on a differential algebraic estimation of the faults dynamics in the stationary reference frame. The method is presented and analysed under the assumption of a single sensor fault (offset or gain). Simulation and experimental results...
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...
