Adaptive Fractional Hybrid Impedance Control of Rotary Series Elastic Actuator in Flat Terrains
Advanced Intelligent Systems, EarlyView.This article presents an adaptive fractional hybrid impedance control (AFH‐IC) approach for rotary series elastic actuators operating on flat terrains. The proposed method integrates fractional‐order control, adaptive fuzzy logic, and particle swarm optimization to enhance torque tracking accuracy and robustness.

Moduli spaces of meromorphic functions and determinant of Laplacian
, 2014 The Hurwitz space is the moduli space of pairs $(X,f)$ where $X$ is a compact Riemann surface and $f$ is a meromorphic function on $X$. We study the Laplace operator $\Delta^{|df|^2}$ of the flat singular Riemannian manifold $(X,|df|^2)$.

Pervasiveness of the $p$-Laplace operator under localization of fractional $g$-Laplace operators
, 2023 In this work we analyze the behavior of truncated functionals as \begin{equation*} \int_{\mathbb{R}^N}\int_{B(x,δ)} G\left(\frac{|u(x)-u(y)|}{|x-y|^{s}}\right)\frac{dydx}{|x-y|^N}\qquad\text{for }δ\to0^+. \end{equation*} Here the function $G$ is an Orlicz function that in addition is assumed to be a regularly varying function at $0$.

Stochastic Hydrodynamic Velocity Field and the Representation of Langevin Equations
Annalen der Physik, EarlyView.A lumped method is proposed to account for both mean‐field hydrodynamics and stochastic fluctuations within the kinematic equations of motion, providing a regularized formulation of the overdamped approximation. The concept of stochastic realizability in broad sense is introduced based on the spectral properties of the Fredholm operator associated with

Output feedback robust stabilization of distributed‐order systems
Asian Journal of Control, EarlyView.Abstract This paper addresses the challenge of robust fast stabilization for a class of dynamical systems characterized by slow and ultra‐slow dynamics. The system model is approximated using a distributed‐order derivative of the measured output, which captures the influence of the control input, system dynamics, and external disturbances.

Bohr phenomena for Laplace-Beltrami operators
Indagationes Mathematicae, 2006 AbstractWe investigate a Bohr phenomenon on the spaces of solutions of weighted Laplace-Beltrami operators associated with the hyperbolic metric of the unit ball in ℂN. These solutions do not satisfy the usual maximum principle, and the spaces have natural bases none of whose members is a constant function.

Infinitesimal aspects of the Laplace operator
, 2000 In the context of synthetic differential geometry, we study the Laplace operator an a Riemannian manifold. The main new aspect is a neighbourhood of the diagonal, smaller than the second neighbourhood usually required as support for second order ...
