摘要
该文将温室中的作物生长、环境控制和经济分析置于一个大系统下进行研究 ,根据光合速率、环境控制和控制成本三个子模型以及它们之间的关系构造了温室的综合动态模型 ;将大系统控制论中的“分解—协调”方法应用于求解温室系统的全局最优化问题 。
Putting the growth of plants, environmental control and economic analysis of greenhouse in a lange scale system, the comprehensive dynamic model of gneenhouse was developed. The model was constructed basing on three sub models and the relationships among the rate of photosynthetic, environmental control and control cost. The “decomposition coordination” method of large scale systems cybernetics was employed to solve the question of the overall optimization of greenhouse systems, and optimum means of comprehensive environmental control under different external climate conditions is obtained while better control and lower cost are simultaneously gained.
