About the loss of robustness of the LQG/LTR compensator [PDF]
INCAS BulletinIt is known that the optimal LQR regulator (Linear Quadratic Regulator) with full state feedback has remarkable robustness properties, defined by gain margins of (1/2, ) and phase of at least ± 60 degrees.

Policy Evaluation in Distributional LQR [PDF]
, 2023 Distributional reinforcement learning (DRL) enhances the understanding of the effects of the randomness in the environment by letting agents learn the distribution of a random return, rather than its expected value as in standard RL.

Convergence of Gradient-based MAML in LQR
2023 62nd IEEE Conference on Decision and Control (CDC), 2023 The main objective of this research paper is to investigate the local convergence characteristics of Model-agnostic Meta-learning (MAML) when applied to linear system quadratic optimal control (LQR). MAML and its variations have become popular techniques for quickly adapting to new tasks by leveraging previous learning knowledge in areas like ...

Naive Exploration is Optimal for Online LQR
CoRR, 2020 We consider the problem of online adaptive control of the linear quadratic regulator, where the true system parameters are unknown. We prove new upper and lower bounds demonstrating that the optimal regret scales as $\widetildeΘ({\sqrt{d_{\mathbf{u}}^2 d_{\mathbf{x}} T}})$, where $T$ is the number of time steps, $d_{\mathbf{u}}$ is the dimension of the
