An extended Perron-Frobenius operator filter for nonlinear state estimation
Yuta Miwa, Yoshihiko Susuki, Shunji Kotsuki
We propose an extended Perron--Frobenius Operator Filter (PFOF) for nonlinear state estimation. The method learns the Perron--Frobenius operator, an infinite-dimensional linear ope…

On Koopman Resolvents and Frequency Response of Nonlinear Systems
Yoshihiko Susuki, Natsuki Katayama, Alexandre Mauroy +1
This paper proposes a novel formulation of frequency response for nonlinear systems in the Koopman operator framework. This framework is a promising direction for the analysis and…
