Dynamic Uncertainty for Compensated Second-Order Systems [PDF]

open access: yesSensors, 2010
The compensation of LTI systems and the evaluation of the according uncertainty is of growing interest in metrology. Uncertainty evaluation in metrology ought to follow specific guidelines, and recently two corresponding uncertainty evaluation schemes ...

Nonlinear Systems of Second-Order ODEs [PDF]

open access: yesBoundary Value Problems, 2008
We study existence of positive solutions of the nonlinear system −(p1(t,u,v)u′)′= h1(t)f1(t,u,v) in (0,1); −(p2(t,u,v)v′)′=h2(t)f2(t,u,v) in (0,1); u(0)=u(1)=v(0)=v(1)=0, where p1(t,u,v)=1/(a1(t)+c1g1(u,v)) and p2(t,u,v)

On Mixed Problems for Quasilinear Second-Order Systems

open access: yesInternational Journal of Differential Equations, 2010
The paper is devoted to the study of initial-boundary value problems for quasilinear second-order systems. Existence and uniqueness of the solution in the space 𝐻𝑠(Ω×[0,𝑇]), with 𝑠>𝑑/2+3, is proved in the case where Ω is a half-space of ℜ𝑑.

On Second-Order Cone Positive Systems [PDF]

open access: yesSIAM Journal on Control and Optimization, 2021
Internal positivity offers a computationally cheap certificate for external (input-output) positivity of a linear time-invariant system. However, the drawback with this certificate lies in its realization dependency. Firstly, computing such a realization requires to find a polyhedral cone with a potentially high number of extremal generators that lifts

Approximate controllability of second order infinite dimensional systems [PDF]

open access: yesArchives of Control Sciences, 2021
In the paper approximate controllability of second order infinite dimensional system with damping is considered. Applying linear operators in Hilbert spaces general mathematical model of second order dynamical systems with damping is presented.

Stabilization Domains for Second Order Delay Systems

open access: yesIEEE Access, 2021
In this paper, an analytic condition is given for determining delayed positive feedback controller for stabilizing an oscillatory system. The $\tau $ -decomposition and $D$ -decomposition methods are employed in deriving this condition.

Second Order Krotov Method for Discrete-Continuous Systems

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
In the late 1960s and early 1970s, a new class of problems appeared in the theory of optimal control. It was determined that the structure of a number of systems or processes is not homogeneous and can change over time. Therefore, new mathematical models

Second-order Volterra system identification

open access: yesIEEE Transactions on Signal Processing, 2000
The paper deals with second-order Volterra system identification. The system is described as \[ y(n)= h_0+ \sum^\infty_{i=0} h_1(i) u(n- i)+ \sum^\infty_{i= 0} \sum^\infty_{j=0} h_2(i,j) u(n-i) u(n- j)+ \eta(n) \] with input \(u\), output \(y\) and disturbance \(\eta\).
