The invention relates to the technical field of amphibious hybrid power equipment, in particular to an amphibious hybrid power amphibious vehicle navigation power distribution method based on PMP optimization, and the method comprises the steps: constructing an amphibious hybrid power system power source output power relation; based on a PMP theory, constructing a Hamiltonian function of reversible motor power; the dynamic switching condition of the operation mode is determined based on the Hamiltonian function of the reversible motor power, the optimal working value of the final control variable reversible motor power Pm and the optimal working value of the engine power Peng are determined, the key factor that the working change of the power source can induce the change of the switching condition is fully considered, and the problem that the distribution effect is poor due to the fixed switching condition is solved. The Pontryagin minimum principle (PMP) is introduced to optimize the switching condition in real time, and the overall operation efficiency is improved.

    本发明涉及水陆两栖混合动力设备技术领域,具体涉及一种基于PMP优化的水陆混合动力两栖车航行功率分配方法,包括:构建水陆两栖混合动力系统动力源输出功率关系;基于PMP理论,构造可逆电机功率的哈密顿函数;基于可逆电机功率的哈密顿函数确定运行模式动态切换条件,确定最终控制变量可逆电机功率Pm以及发动机功率Peng的最佳工作值,本申请充分考虑动力源工作变化可诱发切换条件改变的关键因素,针对切换条件固定引发分配效果差的问题,引入了庞特里亚金极小值原理(PMP)对切换条件进行了实时优化,提升整体运行效率。
