Robust Switching Rule Design for Boost Converters with Uncertain Parameters and Disturbances

Abstract and Applied Analysis, 2013
This paper is concerned with the design problem of robust switching rule for Boost converters with uncertain parameters and disturbances. Firstly, the Boost converter is modeled as a switched affine linear system with uncertain parameters and ...

A multi-thread control algorithm with update delays based on event-triggered mechanism

Measurement + Control, 2023
In this paper, an event-triggered mechanism for a class of multi-thread control systems is designed by the relationship between the threshold line and the Lyapunov function and an algorithm is proposed with update delays considered. In order to solve the

Mode Switching Control for Drag-Free Satellite Based on Region of Attraction

Space: Science & Technology, 2023
This paper aims to propose a switching rule to improve the efficiency and stability of the mode switching process for the drag-free satellite. The switching rules will ensure the stability of the different controllers during the switching process. Unlike

Lyapunov Spectrum and the Conjugate Pairing Rule for a Thermostatted Random Lorentz Gas: Kinetic Theory

Physical Review Letters, 1997
for the exponents of systems with more than one pair of exponents. In this paper we present an analytical calculation of the four Lyapunov exponents for a dilute, three-dimensional Lorentz gas with randomly placed hard sphere scatterers, both for an equilibrium system and for a system where the moving particle is placed in a thermostatted applied field.

Dynamic multi‐objective optimisation of complex networks based on evolutionary computation

IET Networks, EarlyView., 2022
Abstract As the problems concerning the number of information to be optimised is increasing, the optimisation level is getting higher, the target information is more diversified, and the algorithms are becoming more complex; the traditional algorithms such as particle swarm and differential evolution are far from being able to deal with this situation ...

Modification of the Logistic Map Using Fuzzy Numbers with Application to Pseudorandom Number Generation and Image Encryption

Entropy, 2020
A modification of the classic logistic map is proposed, using fuzzy triangular numbers. The resulting map is analysed through its Lyapunov exponent (LE) and bifurcation diagrams.

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller

International Journal of Adaptive Control and Signal Processing, EarlyView.
Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...

Mittag–Leffler Stability of a Switched Fractional Gene Regulatory Network Model with a Short Memory

Mathematics
A model of gene regulatory networks with generalized Caputo fractional derivatives with respect to another function is set up in this paper. The main characteristic of the model is the presence of a switching rule, which changes at certain times at both ...

Formation Control of Multi‐Agent System with Local Interaction and Artificial Potential Field

Advanced Robotics Research, EarlyView.
This article proposes a local interaction‐based formation control method for Multi‐Agent system, integrating consensus and leader‐follower strategies with a stress response mechanism—artificial potential field to reduce communication overhead and enable obstacle avoidance. Experimental results on triangular, square, and hexagonal formations confirm its
