双电动轮装载机制动控制策略研究与仿真

Study and simulation on braking control strategy for electric double-wheel loaders

针对如何有效回收再生制动能量,合理分配各轮再生制动力,使制动距离最小且回收最多能量及制动安全的关键问题,以双电动轮装载机车辆为原型,提出了双电动轮驱动车辆的串联制动控制策略.在MATLAB/Simulink环境下建立仿真模型.结果表明,该控制策略能够保证制动安全的前提下有效回收再生制动能量.

To effectively recycle and regenerate energy and rationally allocate regenerative wheel-braking force,such issues as minimal braking distance,maximal recycling energy and braking safety are critically considered.By applying the electric double-wheel loader as an example,a series braking control strategy is proposed for electric-driven double-wheel vehicles.Under the Matlab/SimulinkTM simulation environment,it is indicated from results that this control strategy can effectively recycle and regenerate the braking energy while guaranteeing the braking safety.
