This work deals with a procedure for model re-identification of a process in closed loop with an already existing commercial MPC. The controller considered here has a two-layer structure where the upper layer performs a target calculation based on a

An alternative method to formulate the stable Model Predictive Control (MPC) optimization problem, which allows controlling unstable systems with a large domain of attraction, is presented in this work. Usually, stability is guaranteed by means of an

This paper presents a new dual mode nonlinear model predictive controller (NMPC) that is based on the combination of the finite horizon NMPC with the infinite horizon predictive controller (IHMPC). The resulting nonlinear controller is shown to be st

This paper aims at to propose a benchmark MPC controller to be used in the performance assessment of existing industrial MPC systems. The basic questions are how the performance could be evaluated in a realistic basis and how to judge the performance

Twelve original physical variables of an activated sludge wastewater treatment system are considered. These cross-correlated variables are transformed in new ones that are not correlated by the use of PCA (principal component analysis), a powerful to
