The stabilizing design of model predictive controllers typically requires the addition of a suitable terminal cost function and terminal constraint in the optimization problem. These ingredients can ensure asymptotic stability and recursive feasibility of the controlled system.
However, if the set-point to be tracked is changed, the feasibility can be lost and the stabilizing design may fail.
The objective of the talk is to illustrate this problem and present a novel predictive control technique capable to ensure closed loop asymptotic stability and recursive feasibility under changing set-points.
This technique, known as MPC for tracking, can be applied to linear and non-linear systems. Another interesting properties as, for instance, the enlargement of the domain of attraction or the convergence to the optimal steady state in case of unreachable set-points, will be also presented.
