摘要:

功能设计是复杂系统设计开发中极其重要的任务,需要依靠正向开发方法来保障功能设计的正确性和完整性.为此,以民用飞机的飞行控制系统(飞控系统)为例,提出面向正向开发的功能设计方法.首先,借助系统建模语言建立飞机级到系统级再到部件级的功能需求关系模型;然后,按照SAE ARP4754A 民用飞机系统开发指南中的安全性评估方法分析安全性需求,并结合功能需求构建飞控系统的功能知识集;最后,采用功能单元方块图和功能集成方块图对飞控系统进行功能建模.该方法对复杂系统的功能设计具有借鉴意义.

关键词: 功能设计, 飞行控制系统, 功能需求, 功能模型

Abstract:

Functional design is an extremely important part in the design and development of complex systems. It is necessary to establish a forward development method to ensure the correctness and completeness of functional design. Therefore, taking the flight control system of civil aircraft as an example, a forward development method for functional design is proposed. First, system modeling language is used to establish the functional requirements relationship model from aircraft level to system level and then to item level. Then, the functional requirements are combined with the safety requirements in SAE ARP4754A aircraft development guide to construct the functional knowledge set of the flight control system. Finally, the functional model of the flight control system is established based on functional unit block diagram and functional integration block diagram. This method can be used as a reference for the functional design of complex systems.

Key words: functional design, flight control system, functional requirement, functional model
