摘要
为有效提高城市电动公交车的制动能量回收率,以某一后轮驱动的12m城市电动公交车为对象,对简单并联控制策略进行改进,在后轴气压管路添加调压阀以增加后轮电机制动的比例,进而提高制动能量回收率。在此基础上,提出了新型并联控制策略,并结合非线性规划控制算法,运用Matlab/Simulink软件进行仿真。结果表明,采用新型并联控制策略时制动能量回收率最高可达28.4%,比采用简单并联控制策略时的回收率约高12个百分点。
In order to improve the braking energy recovery rate of electric city buses,a rear-wheel drive 12-meter electric city bus is taken as the object of study and some modifications are made on simple parallel control strategy,including adding a pressure regulating valve in rear axle brake pipeline to increase the proportion of rear wheel motor braking,and hence increase braking energy recovery rate. Then on this basis,a novel parallel control strategy is proposed,and combined with nonlinear programming control algorithm,a simulation is conducted using Matlab / Simulink software. The results show that with the novel parallel control strategy,the braking energy recovery rate can reach up to 28. 4%,a 12 percentage point higher than that with simple parallel control strategy.
