An industrial application of multivariable linear quadratic control to a cement mill
The paper presents the design development of a model-based control algorithm for the regulation of tailings and product flow rates in a cement mill. The control variables are the feed rate and the classifier speed. Experimental results of a full-scale industrial application are reported and discussed with a view to the control of the fineness of the cement.
