Necessary conditions for the stability of one delay systems: a Lyapunov matrix approach

IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2012
Abstract Necessary conditions for the exponential stability of one delay linear systems expressed in terms of the Lyapunov matrix of the system are proved. The effectiveness of the proposed conditions is shown in illustrative examples.

Stability and the matrix Lyapunov equation for discrete 2-dimensional systems

IEEE Transactions on Circuits and Systems, 1986
A necessary and sufficient condition is established for the existence of positive definite solutions to the 2-D Lyapunov equation using properties of strictly bounded real matrices. It is shown that in general the 2-D Lyapunov condition is only sufficient and not necessary for the stability of a 2-D discrete system.

Polynomial approximations of the Lyapunov matrix of a class of time delay systems

IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2009
Abstract A polynomial approximation of the Lyapunov matrix appearing in the complete type Lyapunov Krasovskii functionals associated to a class of retarded time delay systems is proposed. The results are concordant with the available semi-analytic solution.

Second-order n-dimensional systems and the Lyapunov matrix equation

IEEE Transactions on Automatic Control, 1971
Equations analogous to the Lyapunov matrix equation are derived for second-order n -dimensional systems. These are shown to be more readily solvable than the equivalent 2n -dimensional Lyapunov matrix equation.

Solution of the Lyapunov matrix equation for a system with a time‐dependent stiffness matrix

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2003
AbstractThe stability of the linearized model of a rotor system with non‐symmetric strain and axial loads is investigated. Since we are using a fixed reference system, the differential equations have the advantage to be free of Coriolis and centrifugal forces.

Lyapunov's matrix equation with system matrix in companion form

International Journal of Control, 1993
Abstract A simple method for solving Lyapunov's matrix equation for linear continuous systems with the system matrix in companion form is proposed. The method involves the inversion of the Hurwitz matrix. A necessary and sufficient condition for the existence of a solution to the equation is also obtained.

Lyapunov matrix of linear systems with delays: A polynomial approximation

2009 6th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE), 2009
A polynomial approximation of the Lyapunov matrix appearing in the complete type Lyapunov Krasovskii functionals associated to time delay systems of retarded type with multiple arbitrary delays is proposed. Two measures of the quality of the approximation are provided: the first one is an estimate of the error in the derivative and the second one is ...
