Abstract：Aimed at the characteristics of benthic complex environment, such as randomicity, non-linear, variability , difficult to establish exact mathematical model, and so on, incorporating the grey prediction, fuzzy control and the conventional P1D control, a design control method: grey prediction fuzzy PID control was presented. The future change of the controlled system was predicted based on a few detected speed value by the grey prediction model, fuzzy PID control achieved adaptive adjustment by fuzzy reasoning. The simulation results show that this algorithm can eliminate randomicity and can control the grey system effectively. This algorithm has better performance than conventional PID control.
