【摘要】 针对基站机房降温系统具有高度非线性、大时变性的特点,如何有效地控制机房内的温度是机房系统管理过程中面临的难题。基于此,设计了基于变论域模糊PID控制方式下的机房降温系统末端控制器,介绍了其结构及原理,简化了其物理模型,又借助MATLAB Simulink(仿真模块库)及Fuzzy Logic Toolbox(模糊逻辑工具箱)搭建了其仿真模型。通过以上方法,在同一环境条件下仿真了采用PID控制器、模糊PID控制器及变论域模糊PID控制器的控制效果,验证了采用基于变论域模糊PID末端控制器的降温系统自适应能力更强,控制效果更佳。从而为工程应用提供了一定理论基础。更多还原

【Abstract】 Aiming at room cooling system for base station with properties of serious nonlinearity,large time-varying,how to effectively control the temperature in the computer room is a difficult issue in managing the computer system.A fresh-air system based on Variable-Universe Fuzzy PID is designed,and the structural principle is expounded,the physical model is idealized,and the model of Simulink and Fuzzy Logic Toolbox of MATLAB is proposed for simulating model.By those endeavors,the control effect of PID,Fuzzy PID,Variable-Universe Fuzzy PID are concluded under the same circumstances.And the Variable-Universe Fuzzy PID is demonstrated for higher adaptability,better performance,laying the foundation for engineering applications.更多还原
