基于MBSE的民机飞行控制系统架构设计

Design of civil aircraft flight control system architecture based on MBSE

基于模型的系统工程(model-based systems engineering,MBSE)已被广泛应用于复杂系统设计之中。通过构建功能、行为和结构之间的关系,提出一种基于MBSE的多层级递进式架构设计流程。随后,以高度控制需求为导向,对民机飞行控制系统进行了示例化建模。结果表明,基于MBSE的民机飞行控制系统多层级递进式架构设计能够充分发挥数字模型可重用的优势,保证需求与功能、逻辑和物理架构的紧密结合,提高系统设计的可追溯性,可为后续领域层阶段模型设计提架构参考。

Model-based systems engineering(MBSE)has been widely used in complex system design.A multi-level progressive architecture design process based on MBSE is proposed by constructing the relationship between function,behavior and structure.Subsequently,guided by the demand for altitude control,an example modeling of the civil aircraft flight control system is conducted.The results indicate the multi-level progressive architecture design of civil aircraft flight control system architecture based on MBSE leverages the advantages of reusable digital models,ensuring a close integration of requirements with functional,logical,and physical architecture.Meanwhile,the method improves the traceability of system design and provides a architectural reference for subsequent domain level model design.
