Cabin Pressurization Control System Design of Civil Aircraft by Model Based Systems Engineering

摘要

This paper introduces the application of model based systems engineering (MBSE) method in designing cabin pressurization control system (PCS) for civil aircraft. Rhapsody and Simulink are used as the design and simulation tools. Use cases, functions flow, and state-machines of the system are built by corresponding models in three MBSE design phases, i.e. requirements analysis, function analysis and design synthesis. System models are verified by SysML and Simulink collaborative simulation.
