iron ore grinding process control

Aug 01, 2008 Model predictive control is employed to handle the highly interacting multivariable system of grinding process. A three-input three-output model of grinding process is constructed for the high quality requirements of the process studied. Constrained dynamic matrix control is applied in an iron ore concentration plant.
