Optimism-Based Adaptive Regulation of Linear-Quadratic Systems

Faradonbeh, Mohamad Kazem Shirani, Tewari, Ambuj, Michailidis, George

Understand

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 of unknown dynamics parameters (exploration), as well as the regulation of the underlying system (exploitation).
  • To this end, optimism-based methods which bias the identification in favor of optimistic approximations of the true parameter are employed in the literature.
  • A number of asymptotic results have been established, but their finite time counterparts are few, with important restrictions.
