Indian Patent:Sensorless Permanent Magnet Synchronous Motor (PMSM) drive with online stator resistance and load torque estimation. Summary of the invention: Adaptive Extended Kalman filter (EKF) based speed and position sensorless control of PMSM is carried out, with joint estimation of load torque and stator resistance. Estimation of load torque is shown to accommodate an increased bandwidth of speed control loop, thereby improving the transient response to step changes in load. A modified speed PI controller is used to decrease the peak overshoot in speed for step changes in reference speed at light loading, and to allow full load starting of the PMSM drive. Estimation of stator resistance improves speed reference tracking, for variation in stator resistance with continuous loading of the machine. The novelty lies in using a simple adaptive technique for EKF, to improve the accuracy of resistance estimation for variable loading of the machine.
