Hamiltonian and Variational Linear Distributed Systems [PDF]

, 2002
We use the formalism of bilinear- and quadratic differential forms in order to study Hamiltonian and variational linear distributed systems. It was shown in [1] that a system described by ordinary linear constant-coefficient differential equations is ...

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

The 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.

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

IEEE 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.

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

International 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

Agriculture, 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 ...

Input-output linearization and fractional robust control of a non-linear system [PDF]

, 2001
This article deals with the association of a linear robust controller and an input-output linearization feedback for the control of a perturbed and non-linear system.

Boundedness control sets for linear systems on Lie groups

Open Mathematics, 2018
Let Σ be a linear system on a connected Lie group G and assume that the reachable set 𝓐 from the identity element e ∈ G is open. In this paper, we give an algebraic condition to warrant the boundedness of the existent control set with a nonempty interior

An Elastic-Window-Based Method for the Underdetermined Problem in Linear Spectral Unmixing to Enhance the Spatial Resolution of the Normalized Difference Vegetation Index Time Series

Applied Sciences, 2023
Inverting land cover reflectance or derived indices from low-spatial-resolution images to refine the spatial resolution of this data is cost-effective for land surface monitoring applications that face technical or budget limitations. Based on the linear
