【摘要】 针对纯电动汽车回馈制动时能量不能有效回收的问题,采用模糊控制策略调节PWM占空比的方式,对半桥斩波式无刷直流电机的回馈制动进行控制,以提高回馈的电流值。以玛西尔牌纯电动汽车技术参数为依据进行了仿真验证,结果表明,运用模糊控制后的半桥斩波式回馈制动,在一次制动条件下电流回馈效果显著,电池SOC值回升0.03%,为制动能量回收领域的研究提供了理论依据。更多还原

【Abstract】 For regenerative braking of all electric vehicle,energy can not be effectively recovered. The mode of PWM duty ratio has been adjusted to control regenerative braking of half-bridge chopper of a brushless DC motor using the fuzzy logic. Simulation is based on the Mashell all electric vehicle. Results show that using fuzzy logic in regenerative braking of half bridge chopper,the effect is excellent. SOC value of battery picks up 0. 03%. It provides a theoretical basis for braking energy recovery research.更多还原
