摘　　要：针对电动自行车续驶里程不足,首先提出模糊控制策略,选取制动强度、蓄电池SOC、轮毂电机转速为输入量,再生制动力占总制动力的比值作为输出量,设计模糊规则和控制器,在Matlab/Simulink中进行仿真。然后制定试验方案并搭建试验台架,分别采集紧急制动、中轻度制动、下长坡制动三种工况下轮毂电机转速和超级电容电压,推导制动能量回收率。最后对比分析三种工况下试验与仿真效果。结果表明:在确保制动安全的条件下,该策略在三种工况下的回收率分别高于试验结果 2.85%、1.54%、2.48%。Aiming at the lack of driving range of electric bicycle,first the paper puts forward fuzzy control strategy that is selected brake strength,battery SOC,wheel hub motor speed as the input,the ratio of regenerative braking force to total braking force as the output,and designs fuzzy rules and the controller,meanwhile simulated in Matlab/Simulink.Then the test plan and the test bench are set up and deduced the rate of braking energy recovery. The braking speed of the wheel hub motor and the supercapacitor voltage are calculated respectively under the three kinds of working conditions of emergency braking,medium light brake,under long slope brake.Finally,the test and simulation results under three working conditions are compared and analyzed.The results show that under the condition of ensuring the safety of the braking,the recovery rate of the strategy is higher than that of the test by 5%,3% and 3%.
