考虑参数灵敏度的电动汽车回馈制动模糊控制
Fuzzy control method of regenerative braking in electric vehicles considering parameter sensitivity
摘要
Abstract
The influence factors on braking energy feedback in electric vehicles were analyzed. To recycle more energy, a braking force distribution model was established, and a fuzzy controller on braking force distribution was designed, in which the inputs parameters were vehicle speed, braking strength and battery SOC, and output parameter was regenerative braking ratio. The sensitivity analysis of SOC, braking strength and vehicle speed was conducted by adopting a perturbation method, in which energy recovery rate was taken as the evaluation index. The results show that SOC has the greatest impact on energy recovery ratio, and braking strength has the second impact. So the fuzzy rules for the electronic-hydraulic-compound braking force distribution are improved in accordance with the influence weight of each characteristic parameter to the evaluation index. The recovery ratio of regenerative braking energy can be increased effectively by using fuzzy control method, in which the sensitivities of the characteristic parameters are considered.关键词
