Parallels between control PDE's (Partial Differential Equations) and systems of ODE's (Ordinary Differential Equations) [PDF]

System theorists understand that the same mathematical objects which determine controllability for nonlinear control systems of ordinary differential equations (ODEs) also determine hypoellipticity for linear partial differentail equations (PDEs ...

Time and frequency domain analysis of sampled data controllers via mixed operation equations [PDF]

Specification of the mathematical equations required to define the dynamic response of a linear continuous plant, subject to sampled data control, is complicated by the fact that the digital components of the control system cannot be modeled via linear ...

Numerical method for a system of integro-differential equations and convergence analysis by Taylor collocation

Ain Shams Engineering Journal, 2018
In this paper, we present the Taylor polynomial solutions of system of higher order linear integro-differential Volterra-Fredholm equations (IDVFE). This method transforms IDVFE into the matrix equations which correspond to a system of linear algebraic ...

Spectral characteristics of a nonlocal problem for two linear systems of partial differential equations

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
We study the boundary-value problem for a linear system of differential equations written in the form of differential-operator equations $$ aD_t u(t)+bBu(t)=f(t) $$ with nonlocal boundary conditions at $t$.

Parametric analysis of acoustic liner in bicameral duct: An analytical perspective

Partial Differential Equations in Applied Mathematics
Parametric analysis of different choices of acoustic absorbent liners in a bicameral acoustic duct is presented in the current research study. Bicameral is characterized by two expansion chambers but functions as a single duct in practice, that is widely

Piecewise continuous approach to nonlinear differential equations approximation problem of computational structural mechanics

MATEC Web of Conferences, 2018
This paper presents a nonlinear differential equations system piecewise continuous approximation. The piecewise continuous approximation improves piecewise linear approximation through reducing the errors at the boundaries of different linear ...

Constructing and Solving the System of Linear Equations Produced From LFSR Generators

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
  Linear Feedback Shift Register (LFSR) systems are used  widely in stream cipher systems field. Any system of LFSR's which wauldn't be attacked must first construct the system of linear equations of the LFSR unit. In this paper methods are developed
