Research on energy management of parallel hybrid UAVs

针对小型无人直升机能量利用率不高的问题,提出了一种并联型油电混合动力系统。对提出的混合动力系统进行设计和Matlab/Simulink建模,分别用有限状态机能量管理策略和模糊控制能量管理策略进行仿真和分析。结果表明:油电混合动力系统可以满足无人机的负载变化需求;通过能量管理系统的分配,降低了发动机的油耗率,使无人机的续航时间延长50%以上,同时各设备工作于高效状态。

In order to solve the problem of low efficiency of UAVs,a parallel hybrid power system is proposed.The system is designed and modeled on Matlab/Simulink platform,and the finite state machine energy management strategy and fuzzy control energy management strategy are used for simulation analysis.The result shows that the hybrid power system can meet the load requirements of UAVs.Through the distribution of energy management system,the fuel consumption rate of engine is reduced,the endurance time of UAV is extended by more than 50%,and all equipments work in efficient states.
