The Temperature And Humidity Fuzzy PID Compound Control Of Artificial Climate Chamber

Artificial climate chamber is a kind of scientific research experiments to simulate thenatural environment,as the growing of the demand of agricultural products, modern agriculturecontinuously developments rapidly, in this process, the artificial climate chamber gets fully usedand developed, and it has become the most important scientific research equipment in modernagriculture areas, and even in the industry, medicine, forestry, environmental science andbiological genetic engineering and other areas. Temperature and humidity is the importantcontrol parameters of artificial climate chamber. At home and abroad the primary controlalgorithm of artificial climate chamber is the traditional PID technology, In view of theparticularity of the control parameters (nonlinear and hysteresis, etc.) of the artificial climatechamber and the strong dependence of PID control technology to parameters, it is verycomplicated for the system to debug. Therefore, it is imperative to put the new type of intelligentcontrol algorithm to use for in artificial climate chamber control system.As the continuous development of intelligent control technology, fuzzy PID controltechnology is increasingly mature and has been used in several of occasions with good effect. Inview of its good adaptability and strong anti-jamming capability, and considering the specialfunctions (The operation function of Running with different parameters in different period oftime) of the climate chamber which we are coming to discuss, this paper advance a controlalgorithm which is combination of fuzzy control and fuzzy PID control and complete the controlof temperature and humidity. At the same time the paper introduces the design of the softwareand hardware of the control system. After all, we compare the result of the experimentalsimulation and the field data with the traditional PID control effect, and it reflects the advancednature of the algorithm.
