Abstract: The paper deals with the proposed application of a novel technique for Model Predictive Control to a multistage electrometallurgical process. The novel control technique is based upon high speed repetitive simulation of a non-linear state space model of the process including relevant constraints, and searching in a parameterized control space by an efficient optimization routine until an optimal set of control actions has been found. This MPC-technique is not limited to linear processes with quadratic objective functionals and is therefore believed to offer a major improvement to the control of many industrial processes where the standard, linear control solutions fail because of non-linearities and constraints in the process system.
