温室土壤湿度的模糊控制系统研究

Fuzzy Control Systematic Study of Greenhouse Soil Moisture

[目的]现代化的温室是促进农业技术发展的重要标志。然而,目前国内由于地区因素的差异,部分地区存在着操作成本较高、技术人员水平较低等情况,智能温室系统的普及程度低。为了使自动控制技术能在现代温室中发挥作用,温室内的环境条件得以有效地控制,需要大力推广智能温室技术。[方法]设计了一种针对温室土壤湿度的环境测控系统。[结果]该系统采用模糊控制技术,能够对单栋温室的土壤湿度进行测量和控制。通过Matlab对该系统进行模糊规则的设计,并进行模糊控制仿真。[结论]验证了该系统的可行性,并且使温室环境达到预期要求。

[ Objective] Modem greenhouse is an important symbol to promote agricultural technology development. However, regional differences, high cost and low technical level causes great difficulties to popularize system. For using automatic control technology in modem greenhouse and controlling greenhouse environment effectively, the technology should be promoted actively. [ Method ] A measurement and control system for greenhouse soil moisture was designed. [ Result ] The system can measure and control soil moisture of single greenhouse by using fuzzy control technology. The author completed the design of the fuzzy control rules and simulation of the system. [ Conclusion] The feasibility of the system has been verified and has reached the expected requirement.
