H∞ Control of a Cement Mill: an Industrial Application

The paper presents the design procedure of amodel-based control algorithm for the regulation of tailingsand product flow rates in a cement mill. There are a variety ofcontrol strategies that one may consider for mill circuit controland often several methods for implementing each strategy.Ideally, the control strategy selected and methodology used inits implementation should not only optimize circuitperformance in terms of productivity but also be able tooptimize quality. A∞H controller has been applied to millingcircuits and these goals successfully accomplished. If there is asignificant uncertainty in the system controller∞H responseis better than the other articles mentioned in the introduction
