Abstract

Through analyzing the control effect of three different controllers, such as PID, fuzzy control and fuzzy-PID, it was proved that fuzzy-PID parameters self-tuning controller can make central air-conditioning system get well dynamic and steady performance, Simulation results showed that the fuzzy-PID method can restrain its time delay,high inertia and non-linearity. Using fuzzy-PID parameters self-tuning controller has good effect, such as shorter response time, smaller overshoot, better response characteristics and robustness.
