Passivity and passification of time-delay systems
The goal of this paper is to contribute to the further development of delay-dependent passivity and passification of a class of linear time-delay systems. It considers a less restrictive definition of passivity and employs a new state-transformation to exhibit the delay-dependent dynamics. It is shown that the passivity condition can be cast into a linear matrix inequality format. For state feedback passification, it is proven that it is indifferent to use instantaneous or delayed feedback. The case of output feedback passification is also treated using dynamic controllers. Numerical examples are given to illustrate the results.
