Adaptive generalized matrix projective lag synchronization between two different complex networks with non-identical nodes and different dimensions 下载免费PDF全文
<正>The adaptive generalized matrix projective lag synchronization between two different complex networks with non-identical nodes and different dimensions is investigated in this paper.Based on Lyapunov stability theory and Barbalat’s lemma,generalized matrix projective lag synchronization criteria are derived by using the adaptive control method.Furthermore,each network can be undirected or directed,connected or disconnected,and nodes in either network may have identical or different dynamics.The proposed strategy is applicable to almost all kinds of complex networks.In addition,numerical simulation results are presented to illustrate the effectiveness of this method,showing that the synchronization speed is sensitively influenced by the adaptive law strength,the network size,and the network topological structure. 相似文献

A new three-dimensional chaotic system and its modified generalized projective synchronization 下载免费PDF全文
Based on the Chen chaotic system,this paper constructs a new three-dimensional chaotic system with higher order nonlinear term and studies the basic dynamic behaviours of the system. The modified generalized projective synchronization has been observed in the coupled new three-dimensional chaotic system with unknown parameters. Furthermore,based on Lyapunov stability theory,it obtains the control laws and adaptive laws of parameters to make modified generalized projective synchronization of the coupled new three-dimensional chaotic systems. Numerical simulation results are presented to illustrate the effectiveness of this method. 相似文献

Based on the Chen chaotic system, a new four-dimensional hyperchaotic Chen system is constructed, and the basic dynamic behaviours of the system were studied, and the generalized synchronization has been observed in the coupled four-dimensional hyperchaotic Chen system with unknown parameters. The Routh--Hurwitz theorem is used to derive the conditions of stability of this system. Furthermore based on Lyapunov stability theory, the control laws and adaptive laws of parameters are obtained to make generalized synchronization of the coupled new four-dimensional hyperchaotic Chen systems. Numerical simulation results are presented to illustrate the effectiveness of this method. 相似文献

Model and analysis of drain induced barrier lowering effect for 4H--SiC metal semiconductor field effect transistor 下载免费PDF全文
Based on an analytical solution of the two-dimensional Poisson
equation in the subthreshold region, this paper investigates the
behavior of DIBL (drain induced barrier lowering) effect for short
channel 4H--SiC metal semiconductor field effect transistors
(MESFETs). An accurate analytical model of threshold voltage shift
for the asymmetric short channel 4H--SiC MESFET is presented and
thus verified. According to the presented model, it analyses the
threshold voltage for short channel device on the L/a (channel
length/channel depth) ratio, drain applied voltage VDS and
channel doping concentration ND, thus providing a good basis
for the design and modelling of short channel 4H--SiC MESFETs device. 相似文献
