Stability Constraints for Robust Model Predictive Control

Abstract EN

This paper proposes an approach for the robust stabilization of systems controlled by MPC strategies.

Uncertain SISO linear systems with box-bounded parametric uncertainties are considered.

The proposed approach delivers some constraints on the control inputs which impose sufficient conditions for the convergence of the system output.

These stability constraints can be included in the set of constraints dealt with by existing MPC design strategies, in this way leading to the “robustification” of the MPC.
