  abstract     = {{<p>This letter analyzes certainty-equivalence adaptive controllers for sampled-data systems through a data-driven Riccati equation. Extending a recent framework for data-driven adaptive control, the proposed formulation provides the sampled-data counterpart that explicitly accounts for intersample behavior via lifted cost representations. Sufficient conditions are derived to guarantee stability and robustness of the closed-loop system without explicit model knowledge. Furthermore, it is shown that the closed-loop performance approaches that of the model-based sampled-data LQR when a sufficiently rich data set is available.</p>}},
