民用飞机高度控制系统MBSE建模方法

Aiming at the problems in traditional text-based systems engineering methods, such as the difficulty of design document change, weak readability of engineering model and poor reusability of model, a model-based systems engineering (MBSE) modeling method based on DoDAF(department of defense architecture framework) is proposed. The modeling method divides the design modeling process from two dimensions with a total of 10 modules, and combines DoDAF's multi-view to provide a comprehensive three-dimensional description of complex systems, forming a set of logical and modeling-complete MBSE modeling methods. Taking the altitude control system of civil aircraft as an example, this paper uses SysML(systems modeling language) to describe the models under different DoDAF views, and analyzes the modeling of the system. It is verified that the modeling method can well meet the design requirements of complex systems and is suitable for the development of civil aircraft systems.
