DOI: 10.1016/j.ifacol.2019.06.161
Abstract: Abstract In the presence of structural plant-model mismatch, standard real-time optimization (RTO) schemes are prone to compute an operation point that does not coincide with the plant optimum. Modifier Adaptation (MA) methods are RTO variants… read more here.

DOI: 10.1016/j.ifacol.2020.12.357
Abstract: Abstract Economic model predictive control formulations that combine online optimizing control with offset-free methodologies such as modifier adaptation have been proposed recently. These new algorithms are able to achieve asymptotic optimal performance despite the presence… read more here.
