Abstract

In this paper, control strategies of water and fertilizer precision irrigation are studied and water saving requirements are considered in the purpose of achieving accurate control of water and fertilizer ratio in agricultural irrigation and water conserving. This study mainly established a grey prediction model of water and focused on use of fertilizer in irrigation and implementation of fuzzy PID control. On a basis of grey prediction, the speed of water and fertilizer pump has been under fuzzy PID control. It also has made MATLAB simulation, and then applied to some actual projects effectively.
