Abstract:

Aimed at the nonlinearity and complexity of combine control system, the grey prediction theory and the fuzzy PID control ideas were combined, a grey prediction mathematical model was established and a fuzzy PID controller with grey prediction was developed. It was applied to control the feeding quantity of combine. The simulation results showed that the fuzzy PID control algorithm with grey prediction had better performances for the control of the feeding quantity, which could improve the control quality and robustness of traditional PID control and fuzzy PID control. 
