摘要
以增程式燃料电池电动汽车作为研究对象,将有限状态机与恒温器控制策略相结合并通过该策略合理控制燃料电池与电池的工作模式与输出电流。针对策略中燃料电池的输出电流及开启阈值下限,采用了禁忌搜索算法进行了确定与优化。仿真结果表明,所提出的控制策略可以有效分配电池和燃料电池的输出电流,降低整车运行成本。
Taking the extended fuel cell electric vehicle as the research object,the finite state machine is combined with the thermostat control strategy to control the operating mode and output current of fuel cell and battery.Tabu search algorithm is used to determine and optimize the output current of fuel cell and the lower threshold of opening.The simulation results show that the proposed control strategy can effectively distribute the output current of the battery and fuel cell and reduce the running cost of the vehicle.
