Adaptive Tuning of Online Feedback Optimization for Process Control Applications
Marta Zagorowska, Lukas Ortmann, Giuseppe Belgioioso +1
Online Feedback Optimization leverages properties of optimization algorithms to develop controllers for systems with limited model availability, which is often the case in process…
Persistently Exciting Online Feedback Optimization Controller with Minimal Perturbations
Tore Gude, Marta Anna Zagorowska, Lars Struen Imsland
This paper develops a persistently exciting input generating Online Feedback Optimization (OFO) controller that estimates the sensitivity of a process ensuring minimal deviations f…
Sensitivity of Online Feedback Optimization to time-varying parameters
Marta Zagorowska, Lars Imsland
Online Feedback Optimization uses optimization algorithms as dynamic systems to design optimal control inputs. The results obtained from Online Feedback Optimization depend on the…
Tuning of Online Feedback Optimization for setpoint tracking in centrifugal compressors
Marta Zagorowska, Lukas Ortmann, Alisa Rupenyan +2
Online Feedback Optimization (OFO) controllers steer a system to its optimal operating point by treating optimization algorithms as auxiliary dynamic systems. Implementation of OFO…
