轮边电力驱动系统再生制动控制技术研究

摘要

轮边电力驱动系统中的再生制动系统主要涉及制动能量分配控制技术和再生制动能量回收控制技术.轮边电力驱动工程机械采用双向DC/DC变换器,结合电压电流双闭环控制实现超级电容的储能,从而控制再生制动能量的回收.通过MATLAB建模仿真表明,在满足安全制动的前提下,能够实现最大化的能量回收.%The regenerative braking system of wheel-side electric driving system mainly comprises the control technologies for braking energy distribution and regenerative energy recovery. To control the regenerative braking energy recovery, a bi-directional DC/DC converter, together with a double closedloop voltage-current control, is applied for super-capacitor energy storage of relevant construction machinery. By employing MatlabTM modeling and simulation, it is indicated that the energy recovery maximization could be realized to meet the demand on braking safety.
