Abstract
The joint presence of constraints and disturbances can drive a predictive controller to infeasibility and instability. Here it is shown how robustness against persistent bounded disturbances can be provided by adding to the nominal predictive controller a suitable invariance constraint. The proposed technique allows to significantly enlarge the feasibility region with respect to techniques based on constraint restrictions.
