Model Predictive Control for Froth Flotation Plants

described in this paper is the ability to tightly control the pulp levels of the flotation cells. Although simple PID loops are most often implemented, level control is a multivariable control problem due to the interactions between the cells. A case study on multivariable level control is reported for instance in [6].
