Model-Based System Engineering (MBSE) is a method within system engineering that emphasizes the utilization of formalized models to support system design, analysis, validation, and verification, ensuring that all components of the system are appropriately represented within a single model. In this paper, we propose a MBSE approach for the modeling of turbofan engine control system. This method encompasses three stages: requirement analysis, functional analysis, and design synthesis. Furthermore, we use SysML to accomplish an instance of a control system design on Enterprise Architecture based on Harmony-SE. Finally, we propose a method that integrates simulation model with MBSE model to validate the effectiveness of the simulation model and establish a simulation platform.
