Robust performance of sampled-data systems to structured periodic and quasi-periodic uncertainty is considered, and necessary and sufficient conditions are derived. The conditions are finite dimensional, and explicitly computing them is investigated; the results are illustrated with an example. This work is readily extended to yield exact and finite dimensional robust performance conditions for structured arbitrary time-varying uncertainty.
