The contributions discuss the latest findings and techniques in several areas of control theory, including model predictive control, optimal control, observer design, systems identification and structural analysis of controlled systems, addressing both theoretical and numerical aspects and presenting open research direct...

A common way to represent a system's dynamics is to specify how the state evolves in time, but an alternative viewpoint is to specifying how functions of the state evolve in time.

This work proposes an end-to-end deep learning framework to learn the Koop man embedding function and Koopman Operator together, reducing the prediction error by order of magnitude and achieving superior control performance in several nonlinear dynamic systems like damping pendulum, CartPole, and the seven DOF robotic manipulator.

The performance of the proposed system was successfully evaluated in the Tunnel Circuit of the DARPA Subterranean Challenge, where the UAV cooperated with ground robots to precisely localize artifacts in a coal mine tunnel system.

Em seu entendimento, Pallasmaa afirma que a arquitetura é multidimensional.Nesse sentido, o autor enfatiza a importância da dimensão sensorial, e acredita nos sentidos humanos como elementos essenciais à perceção e compreensão dos espaços em sua integralidade.

A bstract Inspired by the universal operator growth hypothesis, we extend the formalism of Krylov construction in dissipative open quantum systems connected to a Markovian bath. Our construction is based upon the modification of the Liouvillian superoperator by the appropriate Lindbladian, thereby following the vectorized Lanczos algorithm and the Arnoldi iteration. This is well justified due to the incorporation of non-Hermitian effects due to the environment. We study the growth of Lanczos coefficients in the transverse field Ising model (integrable and chaotic limits) for boundary amplitude...

The definition and composition of typical smartEnergy systems are reviewed to provide a comprehensive and holistic understanding of smart energy systems.

The penetration of distributed energy resources in electrical grids has been steadily increasing in an effort to reduce greenhouse gas emissions. Inverters, as interfaces between distributed energy resources and grids, have become critical assets in modern power systems. In recent years, the development and application of grid-forming inverters have gained significant traction due to their capability of supporting power grid operations. A comprehensive review of grid-forming inverters is presented for power system applications. A comparison between grid-forming inverters and grid-following inv...

Abstract. Wind energy is foundational for achieving 100 % renewable electricity production, and significant innovation is required as the grid expands and accommodates hybrid plant systems, energy-intensive products such as fuels, and a transitioning transportation sector. The sizable investments required for wind power plant development and integration make the financial and operational risks of change very high in all applications but especially offshore. Dependence on a high level of modeling and simulation accuracy to mitigate risk and ensure operational performance is essential. Therefore...

This review provides a comprehensive overview of the dynamics of low-temperature water electrolyzers and their influence on coupling the three major technologies, alkaline, Proton Exchange Membrane (PEM) and, Anion Exchange Membrane (AEM) with photovoltaic (PV) systems. Hydrogen technology is experiencing considerable interest as a way to accelerate the energy transition. With no associated CO2 emissions and fast response, water electrolyzers are an attractive option for producing green hydrogen on an industrial scale. This can be seen by the ambitious goals and large-scale projects being anno...
