摘　　要：为了解决变风量(VAV)空调房间温度控制系统中非线性、滞后等缺点,采用一种模糊Smith-PID控制策略,通过水域温度控制实验进行验证,并与常规Smith算法在不同温度下的稳定性、鲁棒性等进行比较研究,同时论证了模糊Smith-PID控制算法在空调房间温控系统中的实用性和有效性。实验结果表明,模糊Smith-PID控制算法可使温度控制精度在±0.5℃,验证了该算法的优越性。To resolve the problem of nonlinear and hysteretic temperature controlling of VAV air-conditioned room temperature control system,this paper,establishing a mathematic model under one parameter of temperature,puts forward a fuzzy Smith-PID control policy which is verified by water temperature controlling experiment,and compared with the conventional Smith algorithm over the stability under different temperature and Robust characteristics,demonstrating the practicability and validity of the fuzzy Smith-PID controlling algorithm in room temperature control system.The experiment shows that the controlling precision of the fuzzy Smith-PID controlling algorithm is about ±0.5℃,fully demonstrating the superiority of the algorithm.
