Rhythm motion control in bio‐inspired fishtail based on central pattern generator

open access: yesIET Cyber-systems and Robotics, 2021
The elastic oscillation structure based on central pattern generators (CPGs), which can produce rhythmic motions, is discussed. First, Hopf CPG, the typical CPG model, being a signal generator for the elastic oscillation structure, is analysed via the ...

Multiphysics Simulator for the IPMC Actuator: Mathematical Model, Finite Difference Scheme, Fast Numerical Algorithm, and Verification

open access: yesMicromachines, 2020
The article is devoted to the development and creation of a multiphysics simulator that can, on the one hand, simulate the most significant physical processes in the IPMC actuator, and on the other hand, unlike commercial products such as COMSOL, can use

Oscillation results for certain fractional difference equations

open access: yesJournal of Hebei University of Science and Technology, 2017
Fractional calculus is a theory that studies the properties and application of arbitrary order differentiation and integration. It can describe the physical properties of some systems more accurately, and better adapt to changes in the system, playing an

OSCILLATION THEORY FOR A CLASS OF SECOND ORDER QUASILINEAR DIFFERENCE EQUATIONS

open access: yesTamkang Journal of Mathematics, 1997
In this paper the authors establish necessary and sufficient conditons for the second order quasilinear difference equation  \[\Delta (\alpha_n(\Delta y_n)^{\alpha*})+f(n, y_{n+1})=0\qquad\qquad n\in N(n_0)\qquad\qquad \text{(E)}\] to have various types of nonoscillatory solutions. In addition, in the case when (E) is either strongly superlinear

Spectral and oscillation theory for general second order Sturm-Liouville difference equations [PDF]

open access: yesAdvances in Difference Equations, 2012
Abstract In this article we establish an oscillation theorem for second order Sturm-Liouville difference equations with general nonlinear dependence on the spectral parameter λ. This nonlinear dependence on λ is allowed both in the leading coefficient and in the potential. We extend the traditional notions of eigenvalues and eigenfunctions to

QUALITATIVE THEORY OF PARTIAL DIFFERENCE EQUATIONS (II): OSCILLATION CRITERIA FOR DIRECT CONTROL SYSTEMS IN SEVERAL VARIABLES

open access: yesTamkang Journal of Mathematics, 1995
This paper is concerned with several direct control systems which are described by partial difference equations. By means of an averaging technique and several oscillation criteria for ordinary recurrence relations, we are able to establish several oscillation criteria for these control systems.

A Hybrid Physics-informed Surrogate Model Approach for Xenon-induced Power Oscillation in Nuclear Reactor

open access: yesYuanzineng kexue jishu
The prediction of xenon-induced power oscillations in nuclear reactors is crucial for operational safety and efficiency. However, existing methodologies are often constrained by limitations in model applicability across diverse conditions, high ...

Oscillation and nonoscillation criteria for two-dimensional time-scale systems of first-order nonlinear dynamic equations

open access: yesElectronic Journal of Differential Equations, 2009
Oscillation criteria for two-dimensional difference and differential systems of first-order linear difference equations are generalized and extended to nonlinear dynamic equations on arbitrary time scales.

Asymptotic solutions of forced nonlinear second order differential equations and their extensions

open access: yesElectronic Journal of Differential Equations, 2007
Using a modified version of Schauder's fixed point theorem, measures of non-compactness and classical techniques, we provide new general results on the asymptotic behavior and the non-oscillation of second order scalar nonlinear differential equations on
