High aerodynamic efficiency is a key design driver for airborne wind energy systems as it strongly affects the achievable energy output. Conventional fixed-wing systems generally use aerofoils with a high thickness-to-chord ratio to achieve high efficiency and wing loading. The box wing concept suits thinner aerofoils as the load distribution can b...

The South China Block is located on the eastern margin of the Eurasian Plate and the western margin of the Pacific Plate. The South China Block is currently in a tectonically compressed environment, while the Tibetan Plateau is moving eastward and the Philippine Sea Plate is moving westward from geodetic observations. The South China Block is an id...
Insights into a reference model for school-based approaches to vectors

Abstract The aim of the present paper is to synthesize an adaptive control system with variable adaptation-loop gain to compensate for the plant parametric uncertainty. In contrast to the existing ones, such a system simultaneously (1) includes an algorithm for the automatic calculation of the parameter adjustment law gain in the controller, which ...
Ongoing digitalization accelerates the transformation and integration of physical production and traditional computing systems into smart objects and their interconnectivity, forming the Internet of Things. In manufacturing, the cross-linking of embedded systems creates adaptive and self-organizing Cyber-Physical Production Systems (CPPSs). Owing t...
In today's manufacturing domain, companies need to be able to join the Industry 4.0 paradigm and, more in particular, the Cyber-Physical Systems (CPS) revolution. However, along this transition, often for companies it could be not enough to deploy new digital technologies in their plant, demonstrating a digital technology readiness. They need to be...

The algorithms of model reference parametric adaptation are considered, providing the astaticism and disturbances estimation. The structure of the control system is suggested allowing to design multivariable controllers providing the movement along the specified trajectories for an object described by kinematics and dynamics of mechanical systems i...

A multiagent system in which each of the agents is described by a linear discrete-time model with random perturbations (external random disturbances affecting the plant and measurement noises) is considered. Networked modifications of iterative learning control laws based on minimizing the deviations from a reference model and also based on the the...
With the advance of the fourth industrial revolution, the manufacturing industry is increasingly changing. The intelligent networking of machines and the collection of real-time data opens up new possibilities for data-based decision making. One of those applications is the digital twin. Those are digital copies of physical objects that represent t...

AbstractThe construction of reference models with variable structure providing processes of formation of a reference signal that are quasi-optimal in terms of the operation speed criterion for closed-loop systems of regulation of speed or positioning operating devices of electromechanical control systems is considered. The proposed approach provide...
