温室温度多模糊控制器切换控制研究与实现

Simulation of a Multi-Fuzzy Controller Switching Control of a Greenhouse Temperature System

针对周年生产的温室控温系统在一年四季需要不断更换不同控温方案的问题,设计了一种基于多模糊控制器的切换控制方法。该方法通过对系统整体规划并制定一系列针对不同环境状态的不同控温方式的切换规则,结合对各个设备的模糊控制,实现对整个温室系统温度的实时精准控制。仿真实验结果表明,该方法非常适用于周年生产的温室控温系统,在运行过程中整个系统表现出良好的控制品质,实现了对温室系统经济、有效和节能的控温目的。

This paper designing a fuzzy control based on multi-switching control methods for an annual production of greenhouse temperature control system which has different programs through the year.This method requires an overall planning for the system and decide different switch rules in different environmental states,combined with fuzzy control of individual devices to achieve real-time precision of greenhouse temperature control.Simulation results shows that the method is suitable in the annual production of greenhouse temperature control system and greenhouse temperatures can be really effective and economical,energy-saving controlled.
