Abstract

Abstract:

Systems with delays frequently appear in engineering. Typical examples of time-delay systems are communication networks, chemical processes, and tele-operation systems. The presence of delays makes system analysis and control design much more complicated. In this survey paper, some of the recent results obtainedby the author on H∞ control of time-delay systems were summarized. Theproblems discussed include the standard H∞ control problem, the delay-type Nehari problem, controller parametrisation and controller implementation. Some problems for future research were highlighted.

Key words: standard H∞ control problem; delay-type Nehari problem; modified Smith predictor; chain-scattering approach; controller implementation
