Robustness of sampled-data control to unmodeled high-frequency dynamics
J. H. Dinh and M. E. Sawan, "Robustness of Sampled-Data Control to Unmodeled High-Frequency Dynamics," American Control Conference, 1993, San Francisco, CA, USA, 1993, pp. 129-130
Robustness of sampled-data control designs to unmodeled high-frequency dynamics is studied using singular perturbation theory. When a plant is preceded by a zero-order holder, a direct transmission term of the reduced-order model should be modeled as a delay element in order to ensure robustness.
