The thesis illustrates the principle of the and its application in the system, establishes the simulation model of the vector control system of PMSM based on the EKF and successfully realizes the application of the speedless sensor in motor control. Firstly, based on the mathematic model of permanent-magnet synchronous motor, the PMSM vector control system is built. Secondly, the Extended Kalman Filter is designed for the on-line estimation of the speed and rotor position by only using measurements of the motor voltages and currents.
