By comparing fuzzy-PID control and conventional PID control, finds that the former control has higher precision, smaller overshoot, and the method has favorable adaptability, robustness and disturbance-rejection especially when the parameters of the object are changed, and can effectively control the air conditioning system which is nonlinear, ...
