Data-Driven Control for Linear Discrete-Time Delay Systems

The increasing ease of obtaining and processing data together with the growth in system complexity has sparked the interest in moving from conventional model-based control design toward data-driven concepts. Since in many engineering applications time delays naturally arise and are often a source of instability, we contribute to the data-driven control field by introducing data-based formulas for state feedback control design in linear discrete-time time-delay systems with uncertain delays. With the proposed approach, the problems of system stabilization as well as of guaranteed cost and <tex-math notation="LaTeX">H∞</tex-math> control design are treated in a unified manner. Extensions to determine the system delays and to ensure robustness in the event of noisy data are also provided.
