ARBIZA, M. J.; BANDONI, J. A.  and  FIGUEROA, J. L.. Use of back-off computation in multilevel MPC. Lat. Am. appl. res. [online]. 2003, vol.33, n.3, pp.251-256. ISSN 0327-0793.

The desired operating point in Model Predictive Control is determined by a local steady-state optimization, which may be based on an eco-nomic objective. In this paper we proposes the solu-tion of a linear dynamic back-off problem to obtain a hierarchical scheme that ensures feasible operation in despite of disturbances. This is performed by computing the critical disturbances and expanding the optimization problem to ensure the existence of a control action that ensures the rejection of each perturbation.

Keywords : Model Predictive Control; Process Optimization.
