On the one-shot data-driven verification of dissipativity of LTI systems with general quadratic supply rate function

Abstract

Based on a one-shot input-output set of data from an LTI system, we present a verification method of dissipativity property based on a general quadratic supply-rate function. We show the applicability of our approach for identifying suitable general quadratic supply-rate function in two numerical examples, one regarding the estimation of ${\mathcal{L}}_2$-gains and one where we verify the dissipativity of a mass-spring-damper system.
