Fuzzy Algorithm Design for an Intelligent Environment Controller Used on an Airborne Radar

In order to improve control quality of the environment control system for an airborne radar,a novel intelligent controller is designed.The proposed controller is based on a control strategy combined PID with fuzzy control.This paper gives an introduction to the principle and system components of the intelligent controller and then discusses the temperature control algorithm,which has excellent flexibility,faster response speed,strong anti-disturbance ability and high robustness.The temperature control algorithm can especially apply to control system which has the characteristics of non-linear,time-variable and large time-delay.The experimental results indicated that the environment control system used the new algorithm has a good control performance,which can satisfied cool or heat the airborne equipment.
