Consensus Analysis and Formation Control of Second-Order Multiagent Systems Via Nonlinear Protocol
- Abstract: Huan Pan, Xiaohong Nian, and Ling Guo This paper mainly investigates consensus and formation control of second-order multiagent system with undirected communication graph. A nonlinear protocol is proposed as an extension of general linear protocols that have been widely studied. In order to achieve formation control, a formation control ... [J. Comput. Nonlinear Dynam. 8, 034502 (2013)] published Thu Feb 7, 2013.
Characterization of Flow-Magnetic Field Interactions in Magneto-Hydrodynamic Turbulence
- Abstract: Jacques C. Richard, Gaurav Kumar, Tamas Kalmar-Nagy, and Sharath S. Girimaji We examine the complex nonlinear flow-magnetic field dynamics in magneto-hydrodynamic (MHD) turbulence. Using direct numerical simulations (DNS), we investigate the dynamical interactions subject to the influence of a uniform applied background magnetic field. The initial magnetic and kinetic Reynol ... [J. Comput. Nonlinear Dynam. 8, 031010 (2013)] published Mon Jan 28, 2013.
Reduced Order Model Analysis of Frequency Response of Alternating Current Near Half Natural Frequency Electrostatically Actuated MEMS Cantilevers
- Abstract: Dumitru I. Caruntu, Israel Martinez, and Martin W. Knecht This paper uses the reduced order model (ROM) method to investigate the nonlinear-parametric dynamics of electrostatically actuated microelectromechanical systems (MEMS) cantilever resonators under soft alternating current (AC) voltage of frequency near half natural frequency. This voltage is betwee ... [J. Comput. Nonlinear Dynam. 8, 031011 (2013)] published Mon Jan 28, 2013.
Fractional Hyperchaotic Telecommunication Systems: A New Paradigm
- Abstract: Abolhassan Razminia and Dumitru Baleanu The dynamics of hyperchaotic and fractional-order systems have increasing attracted attention in recent years. In this paper, we mix two complex dynamics to construct a new telecommunication system. Using a hyperchaotic fractional order system, we propose a novel synchronization scheme between recei ... [J. Comput. Nonlinear Dynam. 8, 031012 (2013)] published Mon Jan 28, 2013.
A Partition Expansion Method for Nonlinear Response Analysis of Stochastic Dynamic Systems With Local Nonlinearity
- Abstract: Changqing Bai and Hongyan Zhang This paper focuses on the problem of nonlinear dynamic response variability resulting from stochastic system properties and random loads. An efficient and accurate method, which can be employed to analyze the dynamic responses of random finite element systems with local nonlinearity, is presented in ... [J. Comput. Nonlinear Dynam. 8, 031009 (2013)] published Mon Jan 7, 2013.
Adaptive Finite-Time Synchronization of Non-Autonomous Chaotic Systems With Uncertainty
- Abstract: Mohammad Pourmahmood Aghababa and Hasan Pourmahmood Aghababa Due to its useful applications in real world processes, synchronization of chaotic systems has attracted the attention of many researchers of mathematics, physics and engineering sciences. In practical situations, many chaotic systems are inevitably disturbed by model uncertainties and external dist ... [J. Comput. Nonlinear Dynam. 8, 031006 (2012)] published Wed Dec 19, 2012.
Simple Recipe for Accurate Solution of Fractional Order Equations
- Abstract: Sambit Das and Anindya Chatterjee Fractional order integrodifferential equations cannot be directly solved like ordinary differential equations. Numerical methods for such equations have additional algorithmic complexities. We present a particularly simple recipe for solving such equations using a Galerkin scheme developed in prior ... [J. Comput. Nonlinear Dynam. 8, 031007 (2012)] published Wed Dec 19, 2012.
Nonlinear Dynamic Analysis of a Cracked Rotor-Bearing System With Fractional Order Damping
- Abstract: Junyi Cao, Shiming Xue, Jing Lin, and Yangquan Chen Fatigue cracking of the rotor shaft is an important fault observed in the rotating machinery of key industries, which can lead to catastrophic failure. Nonlinear dynamics of a cracked rotor system with fractional order damping is investigated by using a response-dependent breathing crack model. The ... [J. Comput.

Dynamic Behavior of a Large Ring of Coupled Self-Excited Oscillators
- Abstract: Miguel A. Barron and Mihir Sen Interconnected, self-excited oscillators are often found in nature and in engineered devices. In this work, a ring of van der Pol oscillators, each of which is connected to its immediate neighbors, is considered. The focus is on the emergent behavior of a large number of oscillators. Conditions are ... [J. Comput. Nonlinear Dynam. 8, 034501 (2012)] published Wed Dec 19, 2012.
Adaptive Sliding Mode Control for Synchronization of a Fractional-Order Chaotic System
- Abstract: Chunlai Li, Kalin Su, and Lei Wu This paper proposes a three-dimensional autonomous chaotic system which displays some interest dynamical behaviors such as invariable Lyapunov exponent spectrums and controllable signal amplitude. The corresponding fractional version of the proposed system is obtained. A single state controller for ... [J. Comput. Nonlinear Dynam. 8, 031005 (2012)] published Wed Nov 28, 2012.
A Model for Highly Strained DNA Compressed Inside a Protein Cavity
- Abstract: Andrew D. Hirsh, Todd D. Lillian, Troy A. Lionberger, Maryna Taranova, Ioan Andricioaei, and N. C. Perkins Deoxyribonucleic acid (DNA) is a long and flexible biopolymer that contains genetic information. Building upon the discovery of the iconic double helix over 50 years ago, subsequent studies have emphasized how its biological function is related to the mechanical properties of the molecule. A remarka ... [J. Comput. Nonlinear Dynam. 8, 031001 (2012)] published Tue Oct 30, 2012.
A Continuum Based Three-Dimensional Modeling of Wind Turbine Blades
- Abstract: Ahmed H. Bayoumy, Ayman A. Nada, and Said M. Megahed Accurate modeling of large wind turbine blades is an extremely challenging problem. This is due to their tremendous geometric complexity and the turbulent and unpredictable conditions in which they operate. In this paper, a continuum based three dimensional finite element model of an elastic wind tu ... [J. Comput. Nonlinear Dynam. 8, 031004 (2012)] published Tue Oct 30, 2012.
Effect of Noise on Generalized Synchronization: An Experimental Perspective

Modeling of a Flexible Instrument to Study its Sliding Behavior Inside a Curved Endoscope
- Abstract: Jitendra P. Khatait, Dannis M. Brouwer, Ronald G. K. M. Aarts, and Just L. Herder Flexible instruments are increasingly used to carry out surgical procedures. The instrument tip is remotely controlled by the surgeon. The flexibility of the instrument and the friction inside the curved endoscope jeopardize the control of the instrument tip. Characterization of the surgical instrum ... [J. Comput. Nonlinear Dynam. 8, 031002 (2012)] published Tue Oct 30, 2012.
