Integrated digital control of aircraft environmental control system

A new project of aircraft environmental control system for integrated digital control with hardware and software was proposed. The feasibility was validated in principle by ground test of an advanced air fighter ECS after computer simulation design. The new integrated digital control system with fuzzy control and the old PID control methods were compared in ground test. Fuzzy control method has fast response and good steady precision for aircraft ECS real time control. It is demonstrated that the improved actual aircraft ECS can satisfy the design demands of aircraft function subsystem.
