The Research of Flux-Weaken Control about IPMSM of the Electric Cars
Abstract:
In this paper, we study the flux-weaken control with the method of the advanced angle of currents in the interior permanent magnet synchronous motor of the electric cars. We adopt the first-order digital filter to handle the data acquired from three phase currents and realize the speed and current double closed loop control by the incremental PI regulation. In Matlab/Simulink, we build the flux-weaken control system simulation model with the double closed loop. For the 40kw IPMSM, we develop the experimental platform based on TMS320F28335. The simulation and experiment archive a good control effect.
