A method for constructing an optimal control strategy in a linear terminal problem

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2021
This paper deals with an optimal control problem for a linear discrete system subject to unknown bounded disturbances, where the control goal is to steer the system with guarantees into a given terminal set while minimising the terminal cost function. We

Internal model control of valve-controlled asymmetric cylinder system based on sectional neural network inverse system

open access: yesThe Journal of Engineering, 2020
In order to improve the control performance of the valve-controlled asymmetric cylinder system with negative overlap, it is proposed that the complex nonlinear system is transformed into a linear system based on the neural network inverse system.

Linear and Branching System Metrics [PDF]

open access: yes, 2009
We extend the classical system relations of trace\ud inclusion, trace equivalence, simulation, and bisimulation to a quantitative setting in which propositions are interpreted not as boolean values, but as elements of arbitrary metric spaces.\ud \ud ...

Task Space Position Control of Slider-Crank Mechanisms Using Simple Tuning Techniques Without Linearization Methods

open access: yesIEEE Access, 2020
In this work, a position control in task space for slider-crank mechanisms is presented. In order to apply linear controllers it is required to linearize the mechanism dynamics at an equilibrium point.

Non-linear dynamic of rotor-stator system with non-linear bearing clearance [PDF]

open access: yes, 2004
The study deals with a rotor-stator contact inducing vibration in rotating machinery. A numerical rotor-stator system, including a non-linear bearing with Hertz contact and clearance is considered.

Linear Dynamical Systems [PDF]

open access: yesProceedings of the American Mathematical Society, 1976
We consider a probability measure m m on a Hilbert space X X and a bounded linear transformation on X X that preserves the measure. We characterize the linear dynamical systems ( X , m , T ) (X,m,T) for the cases where either

Divisibility of the Second–Order Minors of the Nominators by Minimal Denominators of Transfer Matrices of Cyclic Fractional Linear Systems

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2021
The divisibility of the second-order minors of the numerators of transfer matrices by their minimal denominators for cyclic fractional linear systems is analyzed. It is shown that all nonzero second-order minors of the numerators of the transfer matrices

An Assessment of the Spatial Diversification of Agriculture in the Conditions of the Circular Economy in European Union Countries

open access: yesAgriculture, 2023
The level of agricultural development in European Union countries is characterized by great diversity. This is due to differences in natural conditions, the type of agricultural production, agrarian fragmentation, and the level of economic development ...
