Randomized Algorithms for Data-Driven Stabilization of Stochastic Linear Systems
Mohamad Kazem Shirani Faradonbeh, Ambuj Tewari, George Michailidis
Data-driven control strategies for dynamical systems with unknown parameters are popular in theory and applications. An essential problem is to prevent stochastic linear systems be…
Input Perturbations for Adaptive Control and Learning
Mohamad Kazem Shirani Faradonbeh, Ambuj Tewari, George Michailidis
This paper studies adaptive algorithms for simultaneous regulation (i.e., control) and estimation (i.e., learning) of Multiple Input Multiple Output (MIMO) linear dynamical systems…
Finite Time Adaptive Stabilization of LQ Systems
Mohamad Kazem Shirani Faradonbeh, Ambuj Tewari, George Michailidis
Stabilization of linear systems with unknown dynamics is a canonical problem in adaptive control. Since the lack of knowledge of system parameters can cause it to become destabiliz…
On Adaptive Linear-Quadratic Regulators
Mohamad Kazem Shirani Faradonbeh, Ambuj Tewari, George Michailidis
Performance of adaptive control policies is assessed through the regret with respect to the optimal regulator, which reflects the increase in the operating cost due to uncertainty…
Optimism-Based Adaptive Regulation of Linear-Quadratic Systems
Mohamad Kazem Shirani Faradonbeh, Ambuj Tewari, George Michailidis
The main challenge for adaptive regulation of linear-quadratic systems is the trade-off between identification and control. An adaptive policy needs to address both the estimation…
Finite Time Identification in Unstable Linear Systems
Mohamad Kazem Shirani Faradonbeh, Ambuj Tewari, George Michailidis
Identification of the parameters of stable linear dynamical systems is a well-studied problem in the literature, both in the low and high-dimensional settings. However, there are h…
