Output Regulation of Nonlinear Systems in a Koopman Operator Framework
, 2022 This thesis considers the problem of nonlinear output regulation in a Koopman operator framework. The goal of output regulation is to asymptotically track a reference and/or simultaneously reject a disturbance signal, both generated by some external ...

Feedback Linearisation with State Constraints
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Feedback Linearisation (FBL) is a widely used technique that applies feedback laws to transform input‐affine nonlinear control systems into linear control systems, allowing for the use of linear controller design methods such as pole placement.

Koopman Operator, Geometry, and Learning
, 2020 We provide a framework for learning of dynamical systems rooted in the concept of representations and Koopman operators. The interplay between the two leads to the full description of systems that can be represented linearly in a finite dimension, based on the properties of the Koopman operator spectrum.

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model
Integrative Zoology, EarlyView.UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Extraction of nonlinearity in neural networks with Koopman operator [PDF]
Nonlinearity plays a crucial role in deep neural networks. In this paper, we investigate the degree to which the nonlinearity of the neural network is essential.

Contemporary Accounting Research, EarlyView.ABSTRACT We conduct two experiments to examine whether and how the framing (bonus vs. penalty) of a target‐based incentive contract affects knowledge sharing and knowledge seeking. In the first experiment, we predict and find that penalty‐framed contracts increase employees' stress due to the fear of potential loss, which in turn reduces their ...

Modeling of Nonlinear Dynamical Systems Using Koopman Operator Theory [PDF]
, 2021 The dynamics of most mechanical systems tends to incorporate nonlinearfunctions and behaviors to model complex systems. Due to the complexity of some of these systems, only analytical solutions can be found to model, optimize and control them however the
