本文提出了變風量空調系統中室溫控制方案。針對控制對象的大慣性、大時延特點，
采用了串級控制策略；針對對象的非線性和不確定性，主控器采用了一種新的模糊自整定PID 參數的方式，經仿真驗證，該主控器具有良好的動、靜態性能，特別是在魯棒性方面大大優于常規PID 控制器。

ABSTRACT: A control scheme for room temperature control in Variable Air Volume (VAV)
air-conditioning system is presented in this paper. With regard to large inertial and grand-lag
character of control object, cascade control strategy is applied in the control scheme. Aiming at non-linear and uncertainties of control object, a new kind of controller based on fuzzy self-setting PID parameters is applied in the main controller. The emulation results suggest that the new Fuzzy-PID controller has sound performances both in dynamic and static state. And it makes the cascade system much better as to the character of robust adaptation.
