介绍了一种采用变控制律的新型智能控制器在厂房空调中央监控系统中的应用 ,以取代采用单一 PID控制律的传统空调系统控制器。该系统应用集散控制 ,控制器以 PID控制为基础 ,结合 Fuzzy控制及 Bang-Bang控制技术 ,构成变控制律结构。将该控制器应用于恒温恒湿空气调节中央监控系统控制后 ,可具有控制精度高、响应速度快、对干扰不敏感等优点 ,取得良好的控制效果 A new type of intelligent controller with variable control law is introduced in the central air conditioning system for plant control to replace the traditional air conditioning system controller with a single PID control law. The system uses distributed control, the controller based on PID control, combined with Fuzzy control and Bang-Bang control technology, constitute a variable control law structure. The controller is applied to constant temperature and humidity control of the central air conditioning control system, can have high control accuracy, fast response, insensitive to interference, etc., to obtain good control effect
