Lyapunov Function and Exponential Trichotomy on Time Scales

open access: yesDiscrete Dynamics in Nature and Society, 2011
We study the relation between Lyapunov function and exponential trichotomy for the linear equation 𝑥Δ=𝐴(𝑡)𝑥 on time scales. Furthermore, as an application of these results, we give the roughness of exponential trichotomy on time scales.

A Lyapunov Function and Global Stability for a Class of Predator-Prey Models

open access: yesDiscrete Dynamics in Nature and Society, 2012
We construct a new Lyapunov function for a class of predation models. Global stability of the positive equilibrium states of these systems can be established when the Lyapunov function is used.

Physics-informed transient stability assessment of microgrids

open access: yesiEnergy, 2023
With the integration of a voltage source converter (VSC), having variable internal voltages and source impedance, in a microgrid with high resistance to reactance ratio of short lines, angle-based transient stability techniques may find limitations ...

Computation and Verification of Lyapunov Functions [PDF]

open access: yesSIAM Journal on Applied Dynamical Systems, 2015
Lyapunov functions are an important tool to determine the basin of attraction of equilibria in Dynamical Systems through their sublevel sets. Recently, several numerical construction methods for Lyapunov functions have been proposed, among them the RBF (Radial Basis Function) and CPA (Continuous Piecewise Affine) methods. While the first method lacks a

On the regularization and matrix Lyapunov functions for fuzzy differential systems with uncertain parameters

open access: yesElectronic Research Archive, 2023
In this paper, for a regularized fuzzy system, a generalization of the direct Lyapunov method is adapted on the base of matrix-valued Lyapunov-like functions. First, the new concept of a regularization scheme for fuzzy systems is discussed and the matrix-
