A Wiener Tauberian theorem for operators and functions
(Peer reviewed; Journal article, 2021)We prove variants of Wiener's Tauberian theorem in the framework of quantum harmonic analysis, i.e. for convolutions between an absolutely integrable function and a trace class operator, or of two trace class operators. ... -
Wienerization Based Control of Nonlinear Systems
(Chapter, 2022)We present a novel model approximation scheme, named “wienerization”, of nonlinear time invariant systems that uses the systems' nonlinear equilibria maps as the static nonlinearities of Wiener models. We show conditions ... -
Wienerization of systems in nonlinear control canonical normal form
(Chapter, 2022)We extend the concept of model approximation via wienerization to systems in nonlinear control canonical normal form. We elaborate on the conditions for, and implications of, analytically separating nonlinear input affine ... -
WiGiG som aksessteknologi - et supplement til fiberinfrastruktur?
