The Design and Performance Analysis of Hybrid Dynamical System with Multil-Rotor UAV

摘要: 根据多旋翼无人飞行器现存的缺点和结构特点，为其提出一种油电混合动力系统。对提出的多旋翼无人飞行器混合动力系统进行设计，并使用MATLAB/Simulink软件建立混合动力系统仿真模型，最后进行仿真和性能分析。结果显示该混合动力系统比单台同型二冲程发动机在输出功率相同情况下具备更低的耗油特性，设计的混合动力系统具有较高的可靠性和无须人工充电优点，能够减少多旋翼无人飞行器长航时对电池的依赖和降低对二冲程发动机较高的可靠性要求。

Abstract: According to multi-rotor unmanned aerial vehicle’s disadvantages and the structure characteristic at the present, a hybrid dynamical system is being put forward for solving this relevant issue. Have designed and calculated with the hybrid dynamical system for multi-rotor unmanned aerial vehicle, and used the MATLAB/Simulink software to establish the hybrid dynamical system simulation model, there are some simulation and performance analysis for the hybrid dynamical system’s design. The results show that the hybrid dynamical system has the lower fuel consumption characteristic than single two-cycle engine in the same condition that type and output power and the hybrid dynamical system have the high reliability and without artificial recharge advantages, it also can reduce the multi-rotor unmanned aerial vehicle depending on battery when it needs to fly longer and reduce the demand with two-cycle engine’s reliability.
