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 ...

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.

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.

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 ...

Geometric Approach to Lyapunov Analysis in Hamiltonian Dynamics [PDF]

open access: yes, 2001
As is widely recognized in Lyapunov analysis, linearized Hamilton's equations of motion have two marginal directions for which the Lyapunov exponents vanish.
