Bifurcation Control of an Electrostatically-Actuated MEMS Actuator with Time-Delay Feedback

open access: yesMicromachines, 2016
The parametric excitation system consisting of a flexible beam and shuttle mass widely exists in microelectromechanical systems (MEMS), which can exhibit rich nonlinear dynamic behaviors.

Controlling Fast Chaos in Delay Dynamical Systems [PDF]

open access: yes, 2004
We introduce a novel approach for controlling fast chaos in time-delay dynamical systems and use it to control a chaotic photonic device with a characteristic time scale of ~12 ns.

Longitudinal associations among family environment, neural cognitive control, and social competence among adolescents

open access: yesDevelopmental Cognitive Neuroscience, 2017
During adolescence, prefrontal cortex regions, important in cognitive control, undergo maturation to adapt to changing environmental demands. Ways through which social-ecological factors contribute to adolescent neural cognitive control have not been ...

An approach to chaos in some mixed p-spin models [PDF]

open access: yes, 2012
We consider the problems of chaos in disorder and temperature for coupled copies of the mixed p-spin models. Under certain assumptions on the parameters of the models we will first prove a weak form of chaos by showing that the overlap is concentrated ...

Bifurcation Analysis and 0-1 Chaos Test of a Discrete T System

open access: yesChaos Theory and Applications, 2023
This study examines discrete-time T system. We begin by listing the topological divisions of the system's fixed points. Then, we analytically demonstrate that a discrete T system sits at the foundation of a Neimark Sacker(NS) bifurcation under specific ...

Nonlinear Dynamic Characteristics and Optimal Control of SMA Composite Wings Subjected to Stochastic Excitation

open access: yesShock and Vibration, 2015
A kind of high-aspect-ratio shape memory alloy (SMA) composite wing is proposed to reduce the wing’s fluttering. The nonlinear dynamic characteristics and optimal control of the SMA composite wings subjected to in-plane stochastic excitation are ...

Tuning quantum measurements to control chaos [PDF]

open access: yes, 2017
Environment-induced decoherence has long been recognised as being of crucial importance in the study of chaos in quantum systems. In particular, the exact form and strength of the system-environment interaction play a major role in the quantum-to ...

Neural-Impulsive Pinning Control for Complex Networks Based on V-Stability

open access: yesMathematics, 2020
In this work, a neural impulsive pinning controller for a twenty-node dynamical discrete complex network is presented. The node dynamics of the network are all different types of discrete versions of chaotic attractors of three dimensions.

Controlling halo-chaos via wavelet-based feedback

open access: yesDiscrete Dynamics in Nature and Society, 2002
Halo-chaos in high-current accelerator has become one of the key issues because it can cause excessive radioactivity from the accelerators and significantly limits the applications of the new accelerators in industrial and other fields.
