摘要
为实现电动车制动过程中能量的回馈,提高能量使用效率,同时改善制动情况下的ABS防抱死制动系统安全性能,研究了一种基于再生制动调制方式下的防抱死控制系统。制动过程,将模糊PI控制方法应用于单闭环速度调制,实现不同反馈条件下的PI参数自整定;设计模糊控制器实现对半桥与全桥两种PWM调制方式的分配,以达到制动力矩的非恒定控制,实现了有效的防抱死功能。实验结果证明,制动过程中回路能够对蓄电池反充电;制动力矩相对平稳且非恒定,电动车在不同条件路面行驶时,防抱死性能良好。
In order to realize the energy feedback in the brake process of electrical vehicles to improve the efficiency of energy use, while the safety performance of the anti-locked brake system (ABS) could be amel- iorated, a new ABS based on regenerative brake PWM modes was analyzed. In the brake process, self-tun- ing of PI parameters was realized through the application of Fuzzy-PI control method in the single closed-loop speed modulation. To achieve the distribution of half-bridge and full-bridge PWM modes, another Fuzzy con- troller, which resulted in the non continuous control of braking torque and was implemented to achieve the effective anti-locked function, was designed. Experimental results indicated that the anti-locked and regener- ative brake system , which was available despite of different road surface conditions, could charge the battery in return and brake torque turned out to be non-continuous and relatively stable.
