Description
Summary:In the present paper the behavior of the interior permanent magnet synchronous motor (IPMSM) fed by a current controlled voltage source inverter under static and dynamic conditions is presented. A method is explained, which estimates the rotor position angles and rotating speeds at several conditions by measuring the instantaneous values of stator voltages and currents. The estimator is an extended Kalman filter (EKF). The simulation results under four different dynamic conditions, namely the starting, loading of the motor, reversing of speed, and starting with unknown initial rotor position value, are presented.
