基于滑模控制的电动汽车再生制动防抱死研究

摘要

For the function of skid prevention of driving wheel of electric vehicle during regenerative braking on the ice-snow covered road,a single-wheel electric vehicle dynamics model is built. Regenerative ABS controller is designed based on variable structure control theory by voltage-speed regulating mode. Simulation results indicate that this system is of better stability, superior dynamic performance and enough robustness.%为使电动汽车在冰、雪等低附着系数路面上再生制动时,驱动轮具有防抱死功能,建立了单轮电动汽车动力学模型；基于变结构控制理论设计了调压调速型再生ABS控制器；仿真结果表明系统具有良好的稳定性、优越的动态性和足够的鲁棒性.
