function model. The controllers are compared using a rigorous cement mill circuit simulator. The simulations reveal that compared to conventional MPC, soft MPC regulates cement mill circuits better by reducing the ariationsv in manipulated ariablesv by 50%. The performance of MPC with soft constraints is also compared with existing...Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates …
