Dynamic Simulation of Aircraft Environmental Control System Based on Flowmaster

Abstract

The mathematical model and calculation method of three-wheel environmental control system with the highpressure water separation are developed in this paper. The component models are created based on the Flowmaster software platform, and the environmental control system simulation model is established using these component models. The dynamical response of environmental control system is simulated.With the simulation results, a general idea of the dynamical characteristic of the environmental control system can be determined. Then the aircraft cabin temperature control method is developed, which uses expert proportional–integral–derivative to design a coolingpack temperature controller and temperature control table based on fuzzy theory to design the cabin-zone temperature controller. Simulation of this control system is performed based on the established dynamic simulation platform, and the simulation results show that this method has good control effect.
