Every stabilizing dead-time controller has an observer-predictor-based structure. (English) Zbl 1039.93026

The stabilization problem for systems with a single time-delay in the feedback loop is considered. Two state-space parametrizations of the set of all stabilizing dead-time controllers are derived. It is shown that every stabilizing dead-time controller has an observer-predictor-based structure and that the state prediction is a fundamental concept for delay systems.
