Young Researcher Seminar Series

Dr. Efe Balta

ABSTRACT

Optimization-based control methods use feedback information to solve optimal control problems in real-time. It can be difficult to understand the behavior of the closed-loop system, particularly when there is a mismatch between the controller model and the true system. In this talk, we will discuss robust online optimization methods as feedback controllers that learn from online measurements to solve an optimization problem with the physical system. One such method is optimization-based iterative learning control (OB-ILC), which efficiently balances model information and feedback information. We will discuss the OB-ILC approach and its performance guarantees in the context of model mismatch, with applications in advanced manufacturing. Additionally, we will explore how various popular data-driven statistical learning methods can be used in similar settings. Finally, we will look at extensions and future directions leveraging digital twins for optimization and control, with applications in additive manufacturing and precision motion control.
