Decoupling Control of Aircraft Environmental Control System with High Pressure Water Separation

Aircraft environmental control system(ECS) with high pressure water separation is a representative complex coupling control system of MIMO. Flight-tests proved that the controlling means with conventional PID control could not refrigerate the electronic equipment and the cabin satisfactorily. An attempt was made to use the controlling means of output feedback and static decoupling to improve the actual aircraft ECS. Through computer simulation, it was demonstrated that the improved aircraft ECS can satisfy the system design demands.
