摘要
为满足大型无人飞艇多功能、高安全性、高可靠性的要求,开展大型无人飞艇飞行控制与管理系统的架构设计。首先,根据需求捕获的原则完成从飞艇级分解到飞行控制与管理系统级的功能分配,并基于功能架构进行物理架构的分析。然后,使用功能危险分析和故障树分配方法对系统的安全性进行分析,得到系统要进行余度设计的需求;并在可靠性、经济性和质量的约束下,使用多目标差分优化算法进行系统的余度架构设计,进一步给出余度管理策略。最后,进行系统的可靠性评估。结果表明,所提飞行控制与管理系统的架构设计可满足设计要求,该研究可为大型无人飞艇的设计提供参考。
In order to meet the requirements of multifunction,high safety and reliability for large un-manned airships,the architecture design of the flight control and management system(FCMS)for large unmanned airships has been carried out.Firstly,based on the principle of requirements cap-ture,the functional allocation is completed from airship level decomposition to the FCMS level,and physical architecture analysis is conducted based on the functional architecture.Then,the system safety is analyzed using functional hazard analysis(FHA)and fault tree allocation(FTA)methods finding the requirements for redundancy design of the system.Under the constraints of reliability,e-conomy,and weight,a multi-objective differential optimization algorithm is used to design the re-dundancy architecture of the system,and a redundancy management strategy is proposed.Finally,a reliability assessment of the system is implemented.The results indicate that the proposed architec-ture design of the FCMS can meet the design requirements,and this study can provide reference for the design of large unmanned airships.
