为了提高船舶的能源利用效率，降低排放，采用柴油发电机和燃料电池组成的混合动力为船舶提供电能，其中发动机为船舶提供基础载荷，当船舶功率负荷需求大于基础载荷时则由燃料电池组提供剩余的功率。针对这样的混合动力系统，设计船舶的能量管理系统的逻辑门限值控制策略和 PID控制器。仿真结果表明，采用这种混合动力结构的船舶，可以提高柴油机的运行效率，所设计的PID控制器能很好地满足船舶的功率需求，提高系统的稳定性。

In order to improve the energy efficiency and reduce emissions of ships, both of the diesel generator and fuel cell are used to supply power to the hybrid ship, in which the engine provides the basic load, and the rest power is provided by the fu-el cell when the ship power load demand is greater than the basic load.For such a hybrid system, the logic threshold control strategy of energy management system and PID controller are designed.The simulation results show that the running efficiency of diesel engine is improved, which can satisfy the power demand of ship by use of PID controller and improve the stability of the system.
