摘要
在依据能量和物质平衡的温室温度数学模型基础上,建立了温室环境温度模糊专家控制系统的MATLAB仿真模型,包括对控制变量的选取、模糊集的定义、论域等级的划分、隶属函数的选择及模糊控制规则的制定,并用Simulink对控制系统进行了仿真分析。仿真结果证明了该温室环境温度模糊控制策略的有效性及合理性。
According to the theorem of steady thermal equilibrium state in greenhouse, a mathematic model was constructed for the air temperature in the greenhouse. The corresponding fuzzy expert control system for air temperature in greenhouse was established by using the Simulink tools of MATLAB, including the choosing of variables, definition of fuzzy sets, grade partition of the universes, choosing of membership functions and establishment of the fuzzy control rules. And simulations were carried out to analyze the performance of the system. The simulation results testify the validity and reasonability of the fuzzy control strategy for the temperature control in the greenhouse.
