基于模糊逻辑的电动汽车制动能量回馈控制策略

Control Strategy Based on Fuzzy Logic for Regenerative Braking in Electronic Vehicle

在采用交流电机作为电动车和混合动力车的驱动的情况下,针对电动汽车驱动电机的强鲁棒性的需求,提出了一种基于模糊逻辑的控制策略以满足能量回馈的要求,使整车的动力性能、安全性和舒适性达到较好的平衡,同时也估算了这种控制策略的能量回收效率。经仿真和实际测试,结果表明所提策略满足总体设计的性能指标要求。

Aim at robust in moving on motor,a fuzzy logic control strategy is developed for satisfying the requirement of regenerative braking in EV and HEV,making it balance during the power performance,security and comfort while driving.The energy recovery efficiency of the proposed control strategy is also evaluated.The results of simulation and test show that the strategy can satisfy the performance index of whole design significantly.
