直流无刷电机再生制动系统试验台的设计与验证

摘要

基于再生制动理论,以电动汽车用轮毂电机为主体,搭建了直流无刷电机再生制动试验台.以回收能量最大化为目标,提出了相应的再生制动控制策略.结合电机的输出特性和工作原理,利用SIMULINK软件建立了再生制动系统模型.通过模型仿真和试验台试验结果的对比分析,验证了再生制动试验台设计方案的可行性和控制策略的合理性.%Basod on theory of regenerative braking, with electric vehicle hub motor as subject, a brushless DC motor regenerative braking test bench is built. To maximize energy recovery, regenerative braking control strategy is proposed in the paper. In accordance with output characteristic and working principle of motor,regenerative braking system is established with software SIMULINK.By modeling simulation and contrastive analysis of the test result, feasibility of design program of regenerative braking test bench and rationality of control strategy are validated.
