On the Regret of Recursive Methods for Discrete-Time Adaptive Control with Matched Uncertainty

no code implementations2 Apr 2024 Aren Karapetyan, Efe C. Balta, Anastasios Tsiamis, Andrea Iannelli, John Lygeros

Continuous-time adaptive controllers for systems with a matched uncertainty often comprise an online parameter estimator and a corresponding parameterized controller to cancel the uncertainty.

Predictive Linear Online Tracking for Unknown Targets

no code implementations15 Feb 2024 Anastasios Tsiamis, Aren Karapetyan, Yueshan Li, Efe C. Balta, John Lygeros

The learned model is used in the optimal policy under the framework of receding horizon control.

Closed-Loop Finite-Time Analysis of Suboptimal Online Control

no code implementations9 Dec 2023 Aren Karapetyan, Efe C. Balta, Andrea Iannelli, John Lygeros

Finite-time guarantees allow the control design to distribute a limited computational budget over a time horizon and estimate the on-the-go loss in performance due to sub-optimality.

On the Finite-Time Behavior of Suboptimal Linear Model Predictive Control

no code implementations17 May 2023 Aren Karapetyan, Efe C. Balta, Andrea Iannelli, John Lygeros

Inexact methods for model predictive control (MPC), such as real-time iterative schemes or time-distributed optimization, alleviate the computational burden of exact MPC by providing suboptimal solutions.

Online Linear Quadratic Tracking with Regret Guarantees

no code implementations17 Mar 2023 Aren Karapetyan, Diego Bolliger, Anastasios Tsiamis, Efe C. Balta, John Lygeros

Online learning algorithms for dynamical systems provide finite time guarantees for control in the presence of sequentially revealed cost functions.

Implications of Regret on Stability of Linear Dynamical Systems

no code implementations14 Nov 2022 Aren Karapetyan, Anastasios Tsiamis, Efe C. Balta, Andrea Iannelli, John Lygeros

The setting of an agent making decisions under uncertainty and under dynamic constraints is common for the fields of optimal control, reinforcement learning, and recently also for online learning.
