Simulation Research on Variable Arguments PID Hybrid Control for VAV Air Conditioning System

A simplified model of air conditioned room was developed by a typical air conditioning system. Aimed at the feature of big time-lag and inertia, a fuzzy-immune PID controller is proposed. Simulation results compared with the traditional PID controller and fuzzy-immune PID controller prove that the method has many merits including small overshoot, fast response, good self-adaptability, high optimal efficiency, and obviously improving the control performances of the variable frequency air conditioning systems.
