摘　　要：分析了当前几种电动汽车再生制动方式的不足,为防止过大的充电电流对蓄电池造成损害,提出了以蓄电池充电电流为控制对象的再生制动方案。另外,根据电动汽车电机反电动势、电池电压、道路状况,以及初始车速有较大范围变化的特点,设计了电动汽车再生制动H∞鲁棒控制器,并利用SIMULINK建立了电动汽车再生制动系统模型以进行不同条件下的仿真研究,结果表明H∞鲁棒控制器比传统的PI控制器具有更好的稳定性、更强的鲁棒性和抗干扰能力。A novel scheme of regenerative braking of electric vehicle named as Charging Current Control was proposed based on the analysis of deficiency of schemes commonly used to avoid the damage on battery caused by large charging current. The design of H∞ controller for regenerative braking was given to guarantee the robustness of the closed-loop system under the presence of uncertainties, such as large variation of back electromotive force of propulsion motor, voltage of battery, state of road, and initial speed of vehicle. Moreover, the model of regenerative braking was built with SIMULINK, and the simulation results show that the controller based on H∞ theory has better performance of stability, robustness, and disturbance attenuation than traditional PI controller.
