A Type‐3 Fuzzy‐Based Adaptive Sliding Mode Control With Barrier Function for Islanded Hybrid Alternating Current/Direct Current Microgrids With High Renewable Penetration

Energy Science &Engineering, Volume 13, Issue 11, Page 5750-5767, November 2025.
ABSTRACT Microgrids with integrated renewable energy sources are becoming more and more important in the fast‐changing electrical energy production scenario. An 8 kW wind generator and a 4.5 kW solar photovoltaic system are the two renewable energy sources utilized in the hybrid alternating current (AC) and/or direct current (DC) microgrid ...

Scaling Properties of 1D Anderson Model with Correlated Diagonal Disorder

, 2002
Statistical and scaling properties of the Lyapunov exponent for a tight-binding model with the diagonal disorder described by a dichotomic process are considered near the band edge. The effect of correlations on scaling properties is discussed.

Adaptive output feedback control for a class of uncertain non-strict feedback systems with asymmetric time-varying output constraints

Advances in Mechanical Engineering, 2020
This study investigated a novel adaptive output feedback control scheme for non-strict feedback nonlinear systems with uncertainties, disturbances, and asymmetric time-varying output constraints. Because that the states of the system are unmeasurable, we

Cultural transmission and optimization dynamics

, 2002
We study the one-dimensional version of Axelrod's model of cultural transmission from the point of view of optimization dynamics. We show the existence of a Lyapunov potential for the dynamics.

Emergent horizon, Hawking radiation and chaos in the collapsed polymer model of a black hole

, 2017
We have proposed that the interior of a macroscopic Schwarzschild black hole (BH) consists of highly excited, long, closed, interacting strings and, as such, can be modeled as a collapsed polymer. It was previously shown that the scaling relations of the

Progressive Barrier Lyapunov Functions for Nonlinear Constrained Control Systems

This paper introduces the Progressive Barrier Lyapunov Function (p-BLF) for output- and full-state-constrained nonlinear control systems. Unlike traditional BLF methods, where control effort continuously increases as the state approaches the constraint boundaries, the p-BLF maintains minimal control effort in unconstrained regions and increases it ...
