Abstract
Discloses a vector control method for a vehicle permanent magnet synchronous motor based on a DC power, which comprises a current closed-loop adjuster, a modulation index deviation calculator, a current command angle compensator, a current angle preset, a current command angle limit comparator, a current given amplitude compensator and a current given vector corrector. According to the present disclosure, the adjusting direction is always a flux-weakening direction, and instability caused by repeated adjustment will not occur; according to the present disclosure, by introducing the current for simultaneous correction, the voltage saturation-resistant pressure can be shared to the dq current, so that excessive output torque deviation caused by excessive adjustment of a single-axis current can be avoided; the traditional flux weakening target that the system is controlled without losing stability is ensured, and the accuracy of the torque is ensured.
