Process Control. Process control is an engineering mechanism that uses continuous monitoring of an industrial process operational variables (e.g. temperature pressure chemical content) and algorithms and then uses that information to adjust variables to reach product output specifications and objectives.

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.
