Recent work on feedback-based optimization.

Please see the following papers (all very interesting, I think):

* Optimal switching of MPC cost function for changing active constraints. LF Bernardino, S Skogestad. Journal of Process Control 142, 103298. 2024

* Optimal measurement-based cost gradient estimate for feedback real-time optimization LF Bernardino, S Skogestad. Computers & Chemical Engineering, 108815 2024

* Primal-dual feedback-optimizing control with override for real-time optimization R Dirza, S Skogestad. Journal of Process Control 138, 103208 3 2024

* Decentralized control using selectors for optimal steady-state operation with changing active constraints LF Bernardino, S Skogestad. Journal of Process Control 137, 103194 5 2024
