Abstract :
Flux weakening control is an important issue of PMSM for EV. Based on the small signal mode and the transfer function of flux-weakening control of PMSM, the effects of PI parameters of flux weakening control on the dynamic performance of syatem are analyzed and the design method of PI parameters is got. Then the flux-weakening PI controller of fuzzy self-adaptive is designed to enhance the dynamic response speed and reduce the overshoot of flux-weakening control system, which have been validated by the simulation and experiment.
