Determining the domain of attraction of hybrid non–linear systems using maximal Lyapunov functions [PDF]

open access: yes, 2010
summary:In this article a method is presented to find systematically the domain of attraction (DOA) of hybrid non-linear systems. It has already been shown that there exists a sequence of special kind of Lyapunov functions $V_n$ in a rational functional ...

Error analysis of QR algorithms for computing Lyapunov exponents [PDF]

open access: yes, 2001
Lyapunov exponents give valuable information about long term dynamics. The discrete and continuous QR algorithms are widely used numerical techniques for computing approximate Lyapunov exponents, although they are not yet supported by a general error ...

Design of an Adaptive Flux Observer for Sensorless Switched Reluctance Motors Using Lyapunov Theory

open access: yesAdvances in Electrical and Computer Engineering, 2020
This paper proposes an adaptive flux observer for a sensorless switched reluctance motor. The observer adaptive gains are designed using the Lyapunov theory to guarantee both the accuracy and stability of the sensorless control of a switched reluctance

Decentralised DC voltage control and flexible power regulation for multi-port converter-based energy router

open access: yesThe Journal of Engineering, 2019
The idea of ‘energy router’ (ER) is put forward as a critical application of the energy Internet (EI), especially in the new generation of electric power system to fulfil the power management and to deal with the integration of massive distributed ...

The Lyapunov spectrum as the Newton method [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2012
For a class of dynamical systems, the cookie-cutter maps, we prove that the Lyapunov spectrum coincides with the map given by the Newton-Raphson method applied to the derivative of the pressure function.

Solution Bounds and Numerical Methods of the Unified Algebraic Lyapunov Equation

open access: yesMathematics, 2022
In this paper, applying some properties of matrix inequality and Schur complement, we give new upper and lower bounds of the solution for the unified algebraic Lyapunov equation that generalize the forms of discrete and continuous Lyapunov matrix ...

General active stabiliser for coordinated control of low voltage multi-terminal AC/DC hybrid system

open access: yesThe Journal of Engineering, 2018
It is known that if AC/DC converter power exceeds limit it may lead to instability of DC network, especially DC voltage, and further affects the whole system.

Numerical Methods That Preserve a Lyapunov Function for Ordinary Differential Equations

open access: yesMathematics, 2022
The paper studies numerical methods that preserve a Lyapunov function of a dynamical system, i.e., numerical approximations whose energy decreases, just like in the original differential equation.

Event-triggered detection of cyberattacks on load frequency control

open access: yesIET Cyber-Physical Systems, 2020
Modern power systems are extensively interlaced with data communication at various levels leading to increased vulnerability to cyberattacks at individual components as well as integrated controls.

Solution of Positive Periodic Discrete Lyapunov Equations with Applications to the Balancing of Periodic Systems. [PDF]

open access: yes, 1997
The discrete-time positive periodic Lyapunov equations have important applications in the balancing and potentially also in the model reduction of discrete-time periodic systems.
