Functional simulation of the cabin pressure control system based on stateflow

Abstract The cabin pressure control system(CPCS) is an important part of the aircraft environmental control system. In the actual flight process, it needs to achieve different functions according to the working scene. In this paper, the architecture and working principle of the CPCS system are summarized, and the functions of the system are analyzed; the control logic of each function is designed and simulated by the Stateflow platform. The results show that the control logic and its transition constraints designed in this paper can meet the functional requirements of the system, and the dynamic response is rapid, which can be used for the cabin pressure control system of civil aircraft system function design and verification to provide a reference.
