However the state-space model-based predictive controller reduces the complexity compared to that of its counterpart transfer function model. The prediction matrices and the required control law for the cement ball mill grinding circuit are derived as follows which is suggested in .

non-linear model predictive controller NMPC applied to a closed grinding circuit system in the cement industry. A Markov chain model is used to characterize the cement grinding circuit by modeling the ball mill and the centrifugal dust separator. The probability matrices of the Markovian model are obtained through a combination of comminution

This paper focuses on the design of a nonlinear model predictive control NMPC scheme for a cement grinding circuit i.e. a ball mill in closed loop with an air classifier. The multivariable controller uses two mass fractions as controlled variables and the input flow rate
