Software for modeling and analysis of linear systems with delays

Abstract

This paper proposes a new framework for modeling linear time-invariant (LTI) systems with delays. Key benefits of this framework are that it can handle delays in feedback loops, is general enough for most control applications, and lends itself well to computer-aided analysis. The accompanying software tools should facilitate the design of control systems in the presence of delays, as well as stimulate research into efficient numerical algorithms for assessing the properties and performance of such systems.
