【摘要】 针对智能大厦中空调数量多、分布广,以及空调控制对象的大滞后及非线性特性,建立了一种基于智能控制和Lonworks总线的中央空调控制系统。提出了PID控制与智能控制理论中的模糊控制相结合的控制算法并完成了相关软件的设计,给系统带来了良好的鲁棒性。并且利用MCGS工控组态软件对空调控制系统进行了组态实现,证明了该方法的有效性。经过计算机仿真和试验调试,表明了该系统具有较大的实用价值。该系统已应用于图书馆、博物馆等场所,取得的效果极其好。更多还原

【Abstract】 For the abroad distributing of air-conditioners in the intelligent buildings and the nonlinearities of air-conditioner,a central air-conditioner control system based on intelligent control and Lonworks is proposed.PID control and fuzzy control are combined as an algorithm to improve the robustness of the system.MCGS is used to realize the configuration of the air-conditioner system.Through simulation on computer and experiments,the proposed method is proved to be efficient.The system has practical value.It has been used in libraries and museums,and the performance is very good.更多还原
