Research on intelligent control of an agricultural greenhouse based on fuzzy PID control

摘要

With the development of agricultural science and technology in China, the number of greenhouses is increasing rapidly, but the control of greenhouse temperature, the most critical factor in the greenhouse environment, can no longer meet the requirements of the management and operation of agricultural greenhouse by manpower. Therefore, the perfect combination of greenhouse control and intelligent technology has become an urgent demand in the field of agricultural greenhouses. Research on the combination of greenhouse control and intelligent technology will help save human and financial resources and achieve the objectives of more efficient and stable control. Finally, it can guarantee an increase in crop yield and the profit of greenhouse operators. In this study, the temperature control of an agricultural greenhouse based on fuzzy proportion, integration and differentiation (PID) was taken as the research subject and a greenhouse temperature model was constructed by mathematical expression. Finally, simulation effect charts under simple fuzzy control and PID control were obtained, and the results were compared. Finally, it is concluded that fuzzy PID temperature control has the advantages of short response time and stable temperature-control effect, which is the optimal intelligent control mode of an agricultural greenhouse.
