multivariable process control in clinker grinding

  • Multivariable Nonlinear Control of Cement Mills SpringerLink

    Abstract. In this paper multivariable nonlinear control strategies for a cement grinding circuit are studied. It is shown why nonlinear control is requested in order to deal with typical unmeasured perturbations (hardness change of the clinker) and subsequently two alternative strategies are compared a nonlinear predictive controller and a state feedback controller based on Lyapunov design.
