| 摘 要： | 除了开／关控制，常规PID控制器是HVAC系统现场控制中应用最为广泛最基本的控制器，但对于非线性、时变的系统，常规的PID控制则很难达到满意的控制效果。本文提出了自适应模糊PID控制器模型，可以根据系统误差和误差变化率不断对PID控制器的输出进行在线调整。以某空调房间温度控制系统为研究对象，对自适应模糊PID控制器和常规PID控制器进行了对比。计算结果表明，自适应模糊PID控制器具有良好的动、静态性能，并且鲁棒性较强。

| Abstract: | Besides ON/Off controllers, conventional PID controllers are still the dominant controllers in the field control due to their stable behavior in HVAC systems. However, conventional PID controllers fail to reach the satisfied control results for the nonlinear and time-varying system. The adaptive fuzzy PID controller is designed to adjust the output of the controller according to error and change rate of error. A temperature control system in an air-conditioned room is investigated to compare the adaptive fuzzy PID controller with conventional PID controller. The results demonstrate the fine performance and strong robustness of the proposed adaptive fuzzy PID controller. |
