The cement milling circuit can be seen as a two inputs/two outputs system. The designed multivariable control is based on a LQ controller and a Kalman filter. The authors' main goal is to choose the four design parameters (two diagonal weighting matrices) in order to achieve good performances in terms of rise time, deviation and overshoot. The authors have experimented with several selection
