The Grey Prediction Fuzzy PID Control in Auto-drainage System of Mine

摘要

In complex environment, the auto-drainage system of mine is randomicity, non-linear, variability, and so on. For reliable running of auto-drainage system in mine , a design method of the grey prediction fuzzy PID control algorithm that incorporating the grey prediction, fuzzy control and the conventional PID control is presented. This control algorithm predicted the level of water storehouse by the grey prediction, the result can replace measured signal to participate in reasoning by Fuzzy PID Control. The simulation results show that the Grey Prediction can reflect intending change of actual water level. This algorithm has better performance than that of the common PID control algorithm.
