Synthesis of robust discrete systems based on comparison with stochastic model
Journal of Computer and Systems Sciences International - Tập 46 - Trang 843-853 - 2007
The problem of synthesis of the stabilizing control for a discrete linear system with uncertain parameters is considered. The stochastic model of comparison with parametric noise is constructed; the mean-square stability of this model implies the stability of the system with uncertain parameters varying in a given domain. For the case of the state feedback, the methods of synthesis of the robust s...... hiện toàn bộ

Multifunctional logic modules consisting of elements with bilateral conductance
Journal of Computer and Systems Sciences International - Tập 45 Số 1 - Trang 73-76 - 2006
Multifunctional logic modules consisting of elements with bilateral conductance are proposed; when realizing Boolean formulas in the basis {&, v, !} consisting of at most six letters, these modules have no element redundancy. If the basis has more than six letters, then the redundancy does not exceed 33%.
Synthesis of subminimum-time bounded control of system of rigid bodies
Journal of Computer and Systems Sciences International - Tập 47 - Trang 352-361 - 2008
An algorithm of control of a system of rigid bodies in a form of feedback in special coordinates is discussed. The control is bounded, and it is also subminimum-time in the sense that it coincides with the optimal in linear approximation and in the case of a system with one degree of freedom. It is shown that the controller endows the unperturbed motion of the system with the property of asymptoti...... hiện toàn bộ
Designing an Intelligent Control System for a Basic Oxygen Furnace Based on Computer Vision
Journal of Computer and Systems Sciences International - Tập 60 - Trang 995-1004 - 2021
The structure of an intelligent control system for a converter, which includes a subsystem for recognizing and evaluating the slopping of a gas-slag-metallic emulsion in real time based on computer vision by explicit features and a subsystem for predicting slopping by indirect signs, which are most often used to monitor the oxygen-converter process, is proposed. Procedures for forecasting and dete...... hiện toàn bộ
A two-camera based algorithm for 3D reconstruction of a visual scene. Probabilistic approach
Journal of Computer and Systems Sciences International - Tập 48 - Trang 131-138 - 2009
One of the approaches to the problem of 3D reconstruction, based on the probabilistic identification of matched images patches, without using active illumination sources, is addressed. The source data for the algorithm are the vectors that describe the boundaries of image regions obtained in advance by a procedure of segmentation into parts of a constant color and the subsequent vectorization of t...... hiện toàn bộ
On the theory of autonomous angular stabilization systems of missiles for salvo firing
Journal of Computer and Systems Sciences International - Tập 48 - Trang 465-480 - 2009
The system of differential motion equations of athe discrete-continuous model of a rotating elastic missile with a gas jet angular stabilization system is constructed for the motion perturbed by the transverse force pulse at missile leaving the guide line and side thrust component of the jet engine. Based on exact solution, transfer functions of the stabilization systems in the form of the ratio o...... hiện toàn bộ

A motion control for a spherical robot with pendulum drive
Journal of Computer and Systems Sciences International - Tập 52 - Trang 650-663 - 2013
Problems of controlling a spherical robot with pendulum drive are considered. A mathematical model of the dynamics of this robot is constructed and control laws in the form of state feedback that provide robot motion along a given trajectory are synthesized. Results of computer simulation that demonstrate efficiency of the proposed control laws are presented.
Stability Analysis of Dynamic Systems in the Polynomial Vector-Matrix Representation
Journal of Computer and Systems Sciences International - Tập 57 - Trang 171-178 - 2018
This paper suggests frequency-domain stability criteria for homogeneous multiconnected automatic control systems that allow an easy stability analysis of high-order systems of a large dimension. The results are confirmed by mathematical modeling.
