Logarithmic integrals and system dynamics: An analogue of Bode's sensitivity integral for continuous-time, time-varying systems

Research output: Contribution to journalArticle

Abstract

A new time-domain interpretation of Bode's integral is presented. This allows for a generalization to the class of time-varying systems which possess an exponential dichotomy. It is shown that the sensitivity function is constrained, on average, by the spectral values in the dichotomy spectrum of the antistable component of the open-loop dynamics.
