Distributed adaptive event-triggered control for attitude synchronization of multiple spacecraftSpringer Science and Business Media LLC - Tập 95 - Trang 2625-2638 - 2019
Chuang Xu, Baolin Wu, Xibin Cao, Yingchun Zhang
This paper investigates the problem of attitude synchronization tracking of multiple spacecraft in the presence of limited inter-spacecraft communication, model uncertainties and external disturbances. A distributed adaptive event-triggered control scheme for attitude synchronization tracking of multiple spacecraft is proposed. In the proposed control scheme, the controllers are updated in an aper...... hiện toàn bộ
Adaptive dynamic surface control for MEMS triaxial gyroscope with nonlinear inputsSpringer Science and Business Media LLC - Tập 78 Số 1 - Trang 173-182 - 2014
Song, Zhankui, Li, Hongxing, Sun, Kaibiao
An adaptive dynamic surface control algorithm that incorporates adaptive control and fuzzy logic system into the implementation of dynamic surface control for regulating problem of MEMS triaxial gyroscope subject to external disturbance, uncertainty and input uncertainty is developed in this work. To relax the requirement of exact model and obtain fully adaptive property, a fuzzy logic system is i...... hiện toàn bộ
Conformal invariance of Mei symmetry for the non-holonomic systems of non-Chetaev’s typeSpringer Science and Business Media LLC - Tập 69 - Trang 487-493 - 2011
Jianle Cai
The conformal invariance and conserved quantities of Mei symmetry for the non-holonomic systems of non-Chetaev’s type are studied. Firstly, the differential equations of motion of the holonomic systems corresponding to the non-holonomic systems are discussed. Secondly, based on the introduction of an infinitesimal transformation group and its infinitesimal transformation vector of generators, the ...... hiện toàn bộ
Separatrix crossing and symmetry breaking in NLSE-like systems due to forcing and dampingSpringer Science and Business Media LLC - Tập 102 - Trang 2385-2398 - 2020
D. Eeltink, A. Armaroli, C. Luneau, H. Branger, M. Brunetti, J. Kasparian
We theoretically and experimentally examine the effect of forcing and damping on systems that can be described by the nonlinear Schrödinger equation (NLSE), by making use of the phase-space predictions of the three-wave truncation. In the latter, the spectrum is truncated to only the fundamental frequency and the upper and lower sidebands. Our experiments are performed on deep water waves, which a...... hiện toàn bộ
Nonlinear normal modes and band zones in granular chains with no pre-compressionSpringer Science and Business Media LLC - Tập 63 - Trang 359-385 - 2010
K. R. Jayaprakash, Yuli Starosvetsky, Alexander F. Vakakis, Maxime Peeters, Gaetan Kerschen
We study standing waves (nonlinear normal modes—NNMs) and band zones in finite granular chains composed of spherical granular beads in Hertzian contact, with fixed boundary conditions. Although these are homogeneous dynamical systems in the notation of Rosenberg (Adv. Appl. Mech. 9:155–242, 1966), we show that the discontinuous nature of the dynamics leads to interesting effects such as separation...... hiện toàn bộ
Mechanistic mathematical model of kinesin under time and space fluctuating loadsSpringer Science and Business Media LLC - Tập 53 Số 4 - Trang 303-320 - 2008
Hendricks, Adam G., Epureanu, Bogdan I., Meyhöfer, Edgar
Kinesin-1 is a processive molecular motor that converts the energy from ATP hydrolysis and Brownian motion into directed movement. Single-molecule techniques have allowed the experimental characterization of single kinesins in vitro at a range of loads and ATP concentrations, and shown that each kinesin molecule moves processively along microtubules by alternately advancing each of its motor domai...... hiện toàn bộ
The similarity analysis of financial stocks based on information clusteringSpringer Science and Business Media LLC - Tập 85 - Trang 2635-2652 - 2016
Qiang Tian, Pengjian Shang, Guochen Feng
Similarity in time series is an important feature of dynamical systems such as financial systems, with potential use for clustering of series in system. Here, we mainly introduce a novel method: the reconstructed phase space information clustering method to analyze the financial markets. The method is used to examine the similarity of different sequences by calculating the distances between them, ...... hiện toàn bộ
Multiple coherence resonances evoked from bursting and the underlying bifurcation mechanismSpringer Science and Business Media LLC - Tập 100 - Trang 3645-3666 - 2020
Linan Guan, Huaguang Gu, Yanbing Jia
Coherence resonance (CR), which is typical nonlinear phenomenon that noise plays construct roles, has been widely investigated in single neurons at resting state instead of bursting behavior when noise free. In the present paper, multiple CRs evoked from bursting instead of resting state and the underlying bifurcation mechanism are studied in a theoretical neuron model composed of fast subsystem a...... hiện toàn bộ
