Abstract

A controller of brushless dc motor (BLDCM) for electric vehicle is developed based on the mathematical model of BLDCM and special working condition. The drive and control circuit is composed of digital signal processing and EXB841. The paper analyzes the hardware structure of system in detail. Proportional-integral-differential control strategy is adopted in the system. An arithmetic variable velocity prelabeled value is presented, in order to solve regulating rotate speed in large range accurately. The paper also analyzes flux-weakening control in high speed and method of energy regenerative braking when the vehicle is decelerating.
