|
摘要
提出了基于燃料电池的植保无人机混合动力系统。讨论了混合系统方案,建立了燃料电池以及锂电池的系统模型,提出了基于规则的功率跟随能量管理控制策略。通过Matlab/Simulink仿真分析了在植保无人机作业过程中各电源之间的功率分配。结果表明该能量管理系统在满足植保无人机动力需求的前提下,使需求功率在燃料电池以及锂电池之间得到有效分配,提高了燃料电池的燃料利用率,降低了锂电池的充放电次数,从而延长燃料电池以及锂电池的寿命,提高无人机的续航能力。
A hybrid system with fuel cell and lithium battery is proposed, and the models are established. A rule-based power following control strategy is proposed to solve the energy issues for plant protection UAV. The Matlab/Simulink simulation results indicate that the energy management strategy enables the demand power to be effectively distributed between fuel cell and battery under the premise of meeting the power requirement of plant protection UAVS. It can reduce the hydrogen consumption, increase the efficiency of fuel, reduce the number of charge and discharge of lithium battery, prolong the life of fuel cell and lithium battery and improve the endurance of UAVS.
