摘要
为了优化电动汽车复合电源能量管理及其控制,采用Boost变换器和Buck-Boost变换器相结合的并联控制系统.通过基于逻辑门限值控制策略分配时刻变化的需求功率、新型趋近律滑模控制策略控制变换器的导通与关断,实现对电源输出功率的合理分配和精确控制,减少大电流对蓄电池的冲击,避免蓄电池频繁充放电,高效回收制动能量,延长续航里程.通过MATLAB/Simulink和AVL Cruise搭建仿真模型对其加以验证.
In order to optimize the energy management strategy and its control of electric vehicle composite power supply,the parallel control system combining Boost converter and Buck-Boost converter was adopted,and the conduction and shutdown of the converter were controlled by allocating the demand power at any time based on the logic threshold control strategy and the new approach law sliding mode control strategy,so as to realize the reasonable distribution and precise control of the power output power,reduce the impact of large current on the battery,avoid frequent battery charging and discharging,efficiently recover braking energy,and extend the mileage.It was verified by building a simulation model through MATLAB/Simulink and AVL Cruise.
