摘要
运用一种基于能量和物质守恒的温室环境智能化控制的建模思路和方法,分析了温室小气候中辐射、通风、对流和作物蒸腾作用引起的热质交换物理过程,研究和建立了夏季温室温度的动态模型。用Matlab/Simulink软件仿真,验证了动态模型能可靠地估计温室内空气的温度值,为合理调控温室内环境因子提供了借鉴和依据。
Modeling approaches and methods of greenhouse environmental intellectualized control were used on the basis of the balance of energy and substance, the energy and mass exchange physical processes resulted from radiation, ventilation, convection and crop transpiration in the greenhouse were discussed. The dynamic model of the summer greenhouse temperature was studied and built. Matlab/Simulink software simulation was used which proved the dynamic model can evaluate the temperature value of air in the greenhouse reliably, which provided reference for regulating greenhouse environment factors reasonably.
