摘要
针对冰蓄冷空调的运行控制策略复杂、控制效果不佳的问题,文中提出一种基于预估模糊PID的冰蓄冷空调控制系统。该控制系统在PID控制器的基础上加入了Smith预估器,来预测推理PID参数的变化量。并使用控制系统、空气处理装置、风管系统和变风量末端4部分,实现对冰蓄冷空调的实时控制。在正常工作与复杂工况条件下的仿真实验结果表明,所提出的方法具有更快的响应能力和良好的控制效果。
As the ice storage air?conditioner has the problems of complex operation control strategy and poor control effect,an ice storage air?conditioner control system based on predictive fuzzy PID is proposed.The Smith predictor is added into the control system on the basis of PID controller to predict and infer the variable quantity of PID parameters.The real?time control of ice storage air?conditioner is realized by using the four units(control system,air handling device,duct system and variable air volume end).The results of the simulation experiment under the normal working and complex working conditions show that the proposed system has faster response capability and better control effects than the previous system.
