✦ Synopsis

This paper summarizes the stability results already derived for predictive and adaptive predictive control, discusses them from an intuitive and practical implementation perspective and, from the same perspective, illustrates them by means of two simulated examples. In this way it recalls the limits of stability when applying predictive control and how they are related to the modelling errors, which may change as the process dynamics changes. Also it recalls how, by adding adaptation to the predictive scheme, this source of instability may be compensated for. Already within the adaptive predictive formulation it considers the limits of stability for different scenarios, particularly when a reduced-order adaptive predictive model cannot account for unmodelled process dynamics.
