The koopman operator

Web7 Apr 2024 · In this paper, we present a data-driven controller design method for discrete-time control-affine nonlinear systems. Our approach relies on the Koopman operator, which is a linear but infinite-dimensional operator lifting the nonlinear system to a higher-dimensional space. Particularly, we derive a linear fractional representation of a lifted ... Webthe Koopman mode corresponding to the zero eigenvalue of the Koopman operator contains the sign structure indicating the bipartite consensus. Theorem 7. Consider either the dynamics (2) with f 2 S or the dynamics (3) with f 2 S 0. Recall that the full-state observable can be written in terms of the Koopman triple as x (t) = X j =1 e j t' j (x 0 ...

Webwhere K is a so-called Koopman operator ; see also, e.g., [13,14]. Another approach developed in the paper is the investigation of the evolution of the initial wave function, which relates to the construction of the evolution operator by means of the path integrals [15,16]. For the latter example, the initial wave functions are the direct ... WebA spectral analysis of the Koopman operator, which is an infinite dimensional lin-ear operator on an observable, gives a (modal) description of the global behavior of a nonlinear dynamical system without any explicit prior knowledge of its gov-erning equations.
