【Abstract】 In order to improve the dynamic performance and road haul of electric vehicle (EV), a digital control strategy of permanent magnet synchronous motor (PMSM) in EV drive is presented. In the strategy, a fuzzy PI speed controller with the function of adapting parameters is adopted to enhance dynamic response and robustness, a current controller based on SVPWM is designed to improve power supply voltage utilization ration, thereby, road haul of EV is extended. According to the proposed strategy, a digital control system is developed and experimental result proves the strategy.更多还原
