The paper is concerned with optimization problem of controlled stochastic switching systems. A switching system are regulated by the set of stochastic differential equations which initial circumstances to rely on its antecedent behavior and by the limitations on the transitions or switches between operating mode. problems of optimization for switching systems play important role in exploretion of modeling nature appearance with the continuous behavior of changing law of *** general necessary and sufficients conditions of optimality are a significant implement for solution of optimal controlproblems. It is known that the first-order necessary conditions provide a fundamental tools to investigate optimal controlsystems. But sometimes the first-order necessary condition cannot give fairly full information to find the acceptable evidence for optimal solutions. Consequently, along such singular controls additional tests of optimality are required. In this research for delayed stochastic switching systems optimality condition on singular controls is established.

Metaverse of Things should provide interoperability across real and virtual domains for different applications. This technology requires an immersive and responsive user interface, empowered by integration of head-mounted displays, wearable sensors and environmental sensing. In this paper, we propose a new multi-flow control system that allows to translate user behavior and environmental context within both real and virtual space. The key idea behind is to provide a flexible architecture that can be composed by variable set of devices to suit the needs of the target application. We present the practical examples of the possible integration of the Internet of Things systems, head-mounted displays and metaverse applications.

In many industries, the focus of testing is currently shifting away from classical hardware tests to the virtual verification and validation of products. To this end, cosimulation has become a common tool for the simulation and analysis of complexsystems that span multiple engineering domains and usually involve multiple, heterogeneous and application-specific simulation environments. In particular, the so-called explicit cosimulation allows a widespread application since it has minimal requirements regarding the capabilities of the tool interfaces. However, explicit cosimulation also poses a numerical challenge, especially when the system includes stiff coupling loops. The model-based corrector approach presented in Haid et al. (The 5th Joint internationalconference on Multibody System Dynamics, 2018) provides a method for the efficient cosimulation of such systems. In this article, this model-based corrector approach is extended to additional extrapolation methods. By modeling the cosimulation process through a linear recurrence equation and applying it to the two-mass oscillator test model, the influence of model-based correction on the underlying extrapolation methods in terms of stability, accuracy, and error convergence is analyzed. It is shown that adding model-based correction can significantly improve the overall cosimulation, allowing > 10 times larger macrostep sizes or reducing the cosimulation error by a factor of 10 or more in some cases.

Various methods are used to analyze closed systems with park transformations and dynamic links in rotating and stationary coordinate systems. Numerical methods in various mathematical modeling programs are mainly used. In this paper, an attempt is made to use a symbolic-analytical method to analyze such systems. To simplify the calculations and demonstrate the analysis method, an orthogonal system is used, which allows avoiding the second harmonic when considering the system. This method allows constructing a root hodograph and analyzing the stability region when varying parameters, and directly determining the values in the steady state. Additionally, it is possible to use this approach to study non-symmetric systems with negative or zero sequences using symbolic methods, in which case it is necessary to solve a cascade of systems of equations for each harmonic with a given accuracy. It is also possible to obtain a solution for systems with cross feedbacks.

System identification plays a crucial role in modern control techniques, enabling the data-driven learning of input-output maps or mathematical models. However, practical applications face challenges as the actual number of states is often unknown, and observed variables may be limited. Additionally, unstable systems present further difficulties, as their outputs rapidly diverge or saturate, hindering long-term measurement. This paper addresses these challenges by proposing a novel input-aware modeling method for unstable linear systems using data-driven Koopman analysis. Unlike traditional Koopman analysis which focuses solely on state dynamics, our method explicitly incorporates the influence of the input function
$u(t)$
. This enables us to accurately capture the complete behavior of the system, even under the influence of external control signals. By leveraging Koopman operator theory on augmented state-input data, we capture both the intrinsic dynamics and the sensitivity to external control, crucial for accurate prediction and control of unstable systems. This input-aware approach extends the capabilities of data-driven Koopman analysis to improve modeling and control of complex unstable systems in various applications.
The issues of prevention of the consequences of emergencies arising during the operation of radar systems by applying proactive strategies for managing the technical state of complexsystems are considered. The analys...
