| 摘 要： | 温室环境系统是一个多变量、非线性、时变和滞后的系统,各变量之间具有耦合关系,很难建立精确的数学模型。其中,温度和湿度的变化是最基本的因子,对农业作物影响最为显著。为此,采用模糊控制方法,通过建立模糊控制系统模型和对模糊控制器的设计,引入解耦参数,实现了该系统的温湿度解耦控制,使系统的温湿度控制精度大大提高。实验结果表明:当温室温湿度设定值分别为20℃和70%时,温湿度变化超调量较小,控制过程比较平稳,系统环境达到了作物生长的需求。

| Abstract: | In view of greenhouse system that is a multivariable,non linearity,time -varying and hysteretic system,and there are coupling relations between every variable. It is very difficult to establish precise mathematic model. Among them,the change of temperature and humidity is the most basic factor and it is the most significant impact to the crops' growing. So,through using the method of fuzzy control,establishing fuzzy control system model,introducing the decoupling parameters and designing on fuzzy controller... |
