High precision integrated control automation of crop growth experiment environmental factors has become an important platform support for biotechnology research gradually. On the basis of analysis of fusion detection

main parameters of environment of growth of crops

especially on the coupled system of soil-air temperature and humidity

a model-free control method is presented to solve the real-time control problem of main factor of the coupling parameters system. According to the demand of process parameters of crop cultivation in the production environment

this method simulates the expert specification and model-free control principle

the concrete design experimental research is provided for the experimental temperature and humidity coupling effect of environment. The experimental results illustrates the effectiveness of the approach.
