【Abstract】 In response to the problems of occupying more space of control system and weakening reliability of the control system when using position sensors to track the rotor position in rare earth permanent magnet synchronous motors(REPMSM), a new design method for the motor control system is proposed in this paper to achieve the tracking of the REPMSM rotor position without position sensors by injecting high-frequency voltage. A simulation model of the REPMSM and its control system is built for experiments. The simulation experiment results prove that the closed-loop control system of REPMSM designed based on high-frequency injection method can not only achieve high-precision tracking of the position of rare earth permanent magnet rotor body without position sensors, but also enable REPMSM to have good speed regulation performance, which has certain reference value for researchers engaged in REPMSM control.更多还原
