为解决混合动力装甲车辆多动力源输出优化匹配难题,针对一种具有3个动力源的混合动力系统中各动力源的输出特性和驱动电机功率需求特点,制定了具有双层结构的能量管理策略:顶层的系统功率分配策略完成负载功率估计及其在各动力源间的分配;底层的部件级控制策略实现发动机-发电机组和动力电池的优化控制。通过构建一种分布式硬件在环仿真平台对能量管理策略进行仿真验证。结果表明:混合动力系统能够很好地满足负载功率需求,实现了对多个目标的优化控制。

To solve optimal matching problem of involved multi power sources of armored hybrid vehicle,according to the characteristics of multi-power output and workload requirements,the energy management strategy with double layered structure is formulated. The top layer of power system distributes strategy complete the load power estimation and distribution between multi-power. The component control strategy to realize optimal control of engine-generator set and batteries. The power management strategy is proved through the simulation of distributed HIL simulation platform. The results indicated that the load requirements is satisfied commendably by hybrid power system. The optimal control of multiple-target is implemented.
