Abstract :
It is a hot topic that an extended Kalman filter (EKF) is used as speed and position observer in sensorless control of permanent magnet synchronous motor (PMSM). However, the choice of the EKF covariance matrices is still an unsolved problem as the EKF is applied in sensorless drives. In this paper, the parameters of the covariance matrices are tuned based on ant colony algorithm (ACA). The simulation results show the validity of the procedure.
