Feed-forward regulation and control method and device for stabilizing concentration of filling slurry

The invention provides a feed-forward regulation and control method and device for stabilizing the concentration of filling slurry, and the method comprises the following steps: collecting a stirring signal of stirring equipment in a stirring stage in the stirring stage of the preparation of the filling slurry; according to a preset digital relation model, the real-time concentration of the filling slurry is determined through a stirring signal, and the stirring signal needs to be filtered in advance; according to the concentration value of the preset filling slurry, whether the real-time concentration of the filling slurry meets the design requirement for preparation of the filling slurry or not is determined; the controller controls the loops of the first material and the second material, and the controller selects any loop to control the adding and reducing of the loop to adjust the concentration of the filling slurry. By means of the feed-forward regulation and control method for stabilizing the concentra
