基于MBSE的民机系统功能建模方法

Aimming at the problems of long iteration cycle, low development efficiency and model ambiguity in traditional systems engineering, and combining model-based system engineering, the concept of agile system engineering is introduced into the civil aircraft development process, and the system modeling language is used to define a scenario-based functional modeling method. The top-level capability vision of the altitude control use case of the civil aircraft automatic flight control system is analyzed in detail, and the corresponding function model and interface description view are established. This method expands the system function analysis in an iterative manner, which can fully ensure the close integration of requirements and functional models, and is constructing a requirement-oriented functional modeling method that meets the requirements of the civil aircraft system, providing a basis for the architecture design of the civil aircraft system.
