Tuning of extended Kalman filter using grey wolf optimisation for speed control of permanent magnet synchronous motor drive

This paper deals with tuning of extended Kalman filter (EKF) using grey wolf optimisation (GWO) for sensor less speed control of permanent magnet synchronous motor (PMSM) drive. A real-coded GWO is used to optimise the noise covariance matrices of EKF in an off-line manner. The optimised values of these matrices are injected into the filter, thereby ensuring filter stability and accuracy in the estimation of rotor speed, position and machine...
