On the Existence, Uniqueness, and Stability of Periodic Modes of Motion of a Locomotion System with a Mobile Internal Mass
Journal of Computer and Systems Sciences International - Tập 59 - Trang 129-137 - 2020
D. Yu. Knyaz’kov, T. Yu. Figurina
In this paper, we consider the rectilinear motion of a locomotion system consisting of a hull and an internal mass in a resisting medium during periodic movement of the internal mass relative to the hull. The periodic modes of the system’s movement, in which the hull’s speed is also a time periodic function, are studied. The questions of the existence and uniqueness of periodic modes of system mot...... hiện toàn bộ

A model of fuzzy coalition games in problems of configuring open supply networks
Journal of Computer and Systems Sciences International - Tập 48 - Trang 765-778 - 2009
L. B. Sheremetov
Generation of coalitions in multi-agent systems makes it possible to develop effective organizations. A model of a fuzzy cooperative game with coalitions is described. This model extends the model of a fuzzy coalition game with the associated core by introducing individual fuzzy payments and binary values into the fuzzy core for generating effective coalition structure. The model characteristics a...... hiện toàn bộ
Identification of Objects During the Structural and System Monitoring of the Situation
Journal of Computer and Systems Sciences International - Tập 60 - Trang 695-700 - 2021
A. A. Kochkarov, S. N. Razinkov, A. V. Timoshenko, V. A. Shevtsov
Using the criterion of the minimum average risk, the statistically optimal algorithm for identifying objects by the same type of parameters is synthesized for the structural and system monitoring of the situation. In order to reduce computational costs, its quasi-optimal modification is performed, based on the exclusion of significantly different parameter values from the compared arrays.

On supervisory control of mobile platform on four swivel wheels
Journal of Computer and Systems Sciences International - Tập 50 - Trang 325-335 - 2011
Yu. G. Martynenko, I. E. Mitrofanov, E. V. Pis’mennaya, A. M. Formal’skii
A mobile robotic platform with four driving swivel wheels, whose centers are situated at the vertices of a rectangle, is considered. Each of the wheels can rotate about its horizontal axis in a common way, and the plane of the wheel situated in a fork can turn with respect to the platform about the perpendicular axis. These turns and rotations of four wheels are performed using eight drives. The p...... hiện toàn bộ
Consolidation of Individual Rankings by the Method of Branches And Bounds
Journal of Computer and Systems Sciences International - Tập 61 - Trang 981-989 - 2022
V. N. Nefedov, V. A. Osipova
In the problem of collective choice, an algorithm is proposed for constructing an optimal aggregate ranking that is closest to all individual strict rankings in the sense of the Kemeny median. The application of the branch-and-bound method allows problems of large dimensions to be solved and can also be used in the case when individual preferences are arbitrary binary relations.
Adaptive control of microclimate in greenhouses
Journal of Computer and Systems Sciences International - Tập 53 - Trang 896-907 - 2014
D. N. Gerasimov, M. V. Lyzlova
A solution of the problem of adaptive multiple input multiple output of air temperature, air humidity and carbon dioxide concentration for greenhouses is proposed in the paper. The controller synthesis is based on a parametrically uncertain model of the greenhouse microclimate represented by a system of nonlinear differential equations and on the method of controlling cascading systems. Controller...... hiện toàn bộ
Implementation of the temporal reasoning mechanism in modern intelligent systems
Journal of Computer and Systems Sciences International - Tập 46 - Trang 279-294 - 2007
A. P. Ereemev, I. E. Kurilenko
A modern approach to temporal reasoning modeling in intelligent systems designed for dynamic subject domains is considered. Purposes, problems, and principles of construction of temporal reasoning systems are defined.
Game-Theoretic Specificity of a Competitive Allocation of the Frequency Spectrum

Controlling a Satellite using Single-Gimbal Control Moment Gyroscope During Their Spinning and Braking
Journal of Computer and Systems Sciences International - Tập 59 - Trang 289-300 - 2020
V. N. Platonov, A. V. Sumarokov
The capabilities of using single-gimbal control moment gyroscopes (CMGs) for the attitude control of Earth remote sensing (ERS) satellites are studied. The situation of the incomplete spinning of CMGs used for controlling the angular motion of the satellite when these gyros have a different angular momentum is considered. Control algorithms that can be applied in this situation are proposed, and i...... hiện toàn bộ
