【摘要】 本文提出了变风量空调系统中室温控制方案。针对控制对象的大惯性、大时延特点,采用了串级控制策略;针对对象的非线性和不确定性,主控器采用了一种新的模糊自整定PID参数的方式,经仿真验证,该主控器具有良好的动、静态性能,特别是在鲁棒性方面大大优于常规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.
