英文摘要：

The permanent magnet synchronous motor （PMSM） is taken as the control object, and its drive control strategybased on rotor field orientation is investigated. The mathematical model of the PMSM is analyzed. On this basis, the PMSMspeed control strategy based on rotor field orientation is studied, and the regulators of the outer speed loop and inner currentloop were designed. The effectiveness of the whole drive control strategy was verified with system simulation. The results showthat the system has strong anti-interference ability, and excellent dynamic and static performance.
