Abstract
Disclosed is a method for searching a MTPA curve of a vehicle permanent magnet synchronous motor based on a DC power, which includes a current closed-loop adjuster, a current command generator, a current command angle generator, an active power calculator, an active power storage and comparison processor and a current given vector corrector. According to the present disclosure, the tedious manual calibration is relieved, the optimal angle is automatically searched, and the production efficiency is improved; according to the present disclosure, the step size can be arbitrarily set according to the calibration requirements, so as to achieve a higher calibration accuracy.
