"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
acceptable operation under all conditions is achieved with constant
setpoints for the controlled variables. More generally, the idea is to
use the model off-line to find properties of the optimal solution
suited for (simple) on-line feedback implementation"
Oct 2020: Digital lecture on "Nonlinear input transformations for disturbance rejection, decoupling and linearization"
