"The overall goal of my research is to develop simple yet rigorous methods to solve problems of engineering significance"
"We want to find a
self-optimizing control structure where
close-to-optimalo operation under varying conditions is achieved with constant (or slowly varying)
setpoints for the controlled variables (CVs). The aim is to move more of the burden
of economic optimization from the slower time scale of the real-time optimization (RTO) layer to the faster setpoint control layer.
More generally, the idea is to use the model (or sometimes data) off-line to find properties of the optimal solution
suited for (simple) on-line feedback implementation"
13 June 2022: Plenary talk on "Putting optimization into the control layer
using the magic of feedback control", at ESCAPE-32 conference, Toulouse, France
08 Dec. 2021: Plenary talk on "Nonlinear input transformations for disturbance rejection, decoupling and linearization" at Control Conference of Africa (CCA 2021), Magaliesburg, South Africa (virtual)
