Control and Synchronization of the Hyperchaotic Closed-Loop Supply Chain Network by PI Sliding Mode Control [PDF]

International Journal of Industrial Engineering and Production Research, 2022
In this paper, a closed-loop supply chain is modeled based on hyperchaotic dynamics. Then, synchronization of the two hyperchaotic closed loop supply chains is performed with a proportional integral (PI) sliding mode controller design method.

Augmented Neural Lyapunov Control

IEEE Access, 2023
Machine learning-based methodologies have recently been adapted to solve control problems. The Neural Lyapunov Control (NLC) method is one such example.

New chaos function of composition function Gauss map and dyadic transformation map for digital image encryption [PDF]

ITM Web of Conferences
Encryption algorithms mostly use key-streams generated from random number generators. Several recent studies have shown that the random number generator used is a chaos function.

Adaptive Self-Regulation PID Control of Course-Keeping for Ships

Polish Maritime Research, 2020
To solve the nonlinear control problems of the unknown time-varying environmental disturbances and parametric uncertainties for ship course-keeping control, this paper presents an adaptive self-regulation PID (APID) scheme which can ensure the ...

SUMMER POPULATION OF BATS IN PROTECTED AREAS AND THEIR SURROUNDINGS IN THE EAST OF FENNOSCANDIA

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2020
The eastern outskirts of Fennoscandia harbour two protected areas – Vodlozersky and Kenozersky national parks. They are relatively close to each other and occupy vast taiga territories in the Republic of Karelia and the Arkhangelsk Region.

Lyapunov Functionals in Integral Equations

Axioms, 2023
Lyapunov functions/functionals have found their footing in Volterra integro-differential equations. This is not the case for integral equations, and it is therefore further explored in this paper.

Probing phase structure of black holes with Lyapunov exponents

Journal of High Energy Physics, 2022
We conjecture that there exists a relationship between Lyapunov exponents and black hole phase transitions. To support our conjecture, Lyapunov exponents of the motion of particles and ring strings are calculated for Reissner-Nordström-AdS black holes ...

Global asymptotic stabilization of a pendulum using a single Lyapunov proportional bang-bang control strategy

Measurement + Control, 2023
The existence of a Lyapunov function is known to ensure either local or global stability of a system’s equilibrium state. Inspired by the control-Lyapunov method, we here construct a Lyapunov candidate function by analyzing a pendulum system’s total ...
