Delayed Feedback Control near Hopf Bifurcation

open access: yes, 2007
The stability of functional differential equations under delayed feedback is investigated near a Hopf bifurcation. Necessary and sufficient conditions are derived for the stability of the equilibrium solution using averaging theory.

General decay of the solution for a viscoelastic wave equation with a time-varying delay term in the internal feedback

open access: yes, 2012
In this paper we consider a viscoelastic wave equation with a time-varying delay term, the coefficient of which is not necessarily positive. By introducing suitable energy and Lyapunov functionals, under suitable assumptions, we establish a general ...

On stability and controllability of multi-agent linear systems [PDF]

open access: yes, 2016
Recent advances in communication and computing have made the control and coordination of dynamic network agents to become an area of multidisciplinary research at the intersection of the theory of control systems, communication and linear algebra.

Local null controllability of the control-affine nonlinear systems with time-varying disturbances. Direct calculation of the null controllable region

open access: yes, 2017
The problem of local null controllability for the control-affine nonlinear systems $\dot x(t)=f(x(t))+Bu(t)+w(t),$ $t\in[0,T]$ is considered in this paper.

A subalgebra of the Hardy algebra relevant in control theory and its algebraic-analytic properties

open access: yes, 2013
We denote by A_0+AP_+ the Banach algebra of all complex-valued functions f defined in the closed right half plane, such that f is the sum of a holomorphic function vanishing at infinity and a ``causal'' almost periodic function.

NUMERICAL APPROXIMATION OF SPECTRUM FOR VARIABLE COEFFICIENTS EULER-BERNOULLI BEAMS UNDER A FORCE CONTROL IN POSITION AND VELOCITY

open access: yes, 2017
In this paper, we use asymptotic techniques and the finite differences method to study the spectrum of differential operator arising in exponential stabilization of Euler-Bernoulli beam with nonuniform thickness or density that is clamped at one end and ...
