【Abstract】 Due to the large torque coefficient, small torque ripple and ease of control, permanent magnet synchronous motor (PMSM) system has been widely used in many accurate servo control systems. In this paper, the parameters and states of the non-linear PMSM system are estimated with extended Kalman filter. The effectiveness of the method is verified by simulation.更多还原
