摘要
针对中央空调系统的大滞后、时变性和非线性等特点,在中央空调的冷却水系统中采用模糊模型参考学习控制方案。不断修正控制规则改善控制性能,调整模糊控制器的参数,使得对象的输出跟踪参考模型的输出。控制算法由程序实现,以数字语言值为特征,在线推理。仿真采用Simulink中的S函数,仿真结果证明了该控制策略响应速度快、鲁棒性好,能够实现中央空调系统的节能运行。
Aiming at the central air-conditioning system's non-linear,delay,time varying,fuzzy model reference learning control is adopted in central air-conditioning of cooling water system.The control performance is improved by revise control rules constantly.The parameter of fuzzy controler is adjusted,the output of reference model is followed by object.The algorithm of control is realized by program, characterized by linguistic-numeric values,can make inference-online implemented.S-function in Simulink is used for simulating. The results show that the strategy's response is speedy,robustness is better and can achieve energy saving when central air-conditioning is running.
