平流层飞艇多能源的优化管理系统

针对平流层飞艇的长驻空时间和复杂的飞行工况对其能源系统提出的要求,设计了平流层飞艇多能源(包括太阳能,燃料电池,锂离子电池和航空发电机)优化控制系统。结合平台能源特点和飞行任务,设计了静态能源搭载分配方案。采用分布式电源模块布局,提出了能源实时跟踪切换方法,实现动态调度各能源管理单元。通过建立有限状态机模型,结合模型建立动态实时调度方案,既降低了飞行任务与能源优化管理的耦合程度,又保证了实时互操作性。对能量平衡情况进行分析验证,得到满意的结果,对于复杂工况飞行器的能源控制系统具有普遍的参考意义。

Optimization Management System of Multi-energy Control in Stratosphere Airship

To the high demand of Stratosphere airship energy system under state,a multi-energy(solar cell,fuel cell,lithium cell and aviation electrical machine)optimization control system of Stratosphere airship is designed.It consists of static energy loading scheme and dynamic configuration of four kinds of energy sources.Based on the variation of the airship fly moods and system-related energy demands,a finite-state machine is applied to design the real-time tracking arithmetic of energy-switch.The arithmetic can guarantee the independence of the whole energy module as well as the alert of mutual-operation of other parts of the airship system.The verification of the design is also discussed.The research work can also be applied in the energy system of other aircraft with high complexity of flying mode.
