摘要：

Permanent Magnet Synchronous Motor is characterized by high power density, high efficiency and high reliability, and it is superior in many applications. V/f control for PMSM is able to get rid of the expensive rotor position sensor, and it is of great research value. V/f control method for PMSM is investigated in this paper. Firstly, the reason for the instability of the traditional open-loop V/f control is analyzed. A speed closed-loop is introduced to avoid the instability of the system. Meanwhile, in order to enhance the efficiency of the system, a reactive power closed-loop is proposed, which is added to the system. Finally, experimental results are provided to validate the effectiveness of the proposed V/f control method.
