A Survey of Advanced Dynamic Matrix Control Algorithms for Improved Performance

Model Predictive Controllers, specifically Dynamic Matrix Controllers (DMCs), have become widespread in industry. However, they have some drawbacks, particularly when it comes to their tuning and their application to non-linear systems. This paper explores several modifications to the canonical DMC algorithm which aim to improve its performance and applicability in these situations. The formulation of each modification is presented and contrasted to the canonical formulation, and then each is tested against the other in simulation on a variety of linear and non-linear systems.
