Characterization of the parameter-mismatching effect on the loss of chaos synchronization

Physical Review E, 2002
We investigate the effect of the parameter mismatch on the loss of chaos synchronization in coupled one-dimensional maps. Loss of strong synchronization begins with a first transverse bifurcation of a periodic saddle embedded in the synchronous chaotic attractor (SCA), and then the SCA becomes weakly stable. Because of local transverse repulsion of the

A new 5-parameter MOS transistors mismatch model

ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003
A new 5-parameter MOS transistor mismatch model is introduced capable of predicting transistor mismatch with very high accuracy for ohmic and saturation strong inversion regions, including short channel transistors. The new model is based on splitting the contribution of the mobility degradation parameter mismatch into two components, and modulating ...

A Doppler parameter estimation method based on mismatched compression

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
The ground moving target (GMT) model has been widely employed in modern coherent radar systems, such as the synthetic aperture radar (SAR) and the bistatic SAR (BiSAR). For the coherent radar systems, GMT imaging necessitates the compensation of the additional azimuth modulation without a priori knowledge of the GMT's motion parameters. That is to say,

Stability Analysis of Multi-Paralleled VSCs with Mismatched Parameters

2019 IEEE Applied Power Electronics Conference and Exposition (APEC), 2019
This paper investigates the instability problem caused by the circulating current in the multi-paralleled voltage-source converters (VSCs) with mismatched parameters. The circulating current may arise in the paralleled converters due to the differences in the LCL filer parameters or the controller gains.

EFFECTS OF A PARAMETER MISMATCH ON THE SYNCHRONIZATION OF TWO COUPLED CHAOTIC OSCILLATORS

International Journal of Bifurcation and Chaos, 2000
Considering two identical, coupled Rössler systems, the paper first examines the bifurcations through which low-periodic orbits embedded into the synchronized chaotic state lose their transverse stability and produce the characteristic picture of riddled basins of attraction. The paper hereafter addresses the issue of the robustness of the synchronized

Model‐system parameter mismatch in GPC control

International Journal of Adaptive Control and Signal Processing, 1993
AbstractThis paper considers a linear discrete‐time system controlled by a GPC regulator. However the parameters and dynamic order of the system assumed for the regulator design differ from the true parameters. Hence there is a model‐system parameter mismatch.

PARAMETER MISMATCHES AND INVERSE SYNCHRONIZATION IN THE IKEDA MODEL

International Journal of Modern Physics B, 2004
We investigate inverse retarded synchronization between two uni-directionally linearly coupled chaotic non-identical Ikeda models and show that parameter mismatches are of crucial importance to achieve synchronization. We establish that independent of the relation between the delay time in the coupled systems and the coupling delay time, only inverse ...

On Parameter Mismatch for Hidden Markov Models Applied to Indoor Localization

2020 IEEE 23rd International Conference on Information Fusion (FUSION), 2020
Hidden Markov Chains (HMCs) and, more recently, Hidden semi-Markov Chains (HsMCs) have been used by several groups of researchers to provide a model for indoor localization. A homogeneous HMC is completely determined by the state initial probability vector and the state transition probability matrix.

Synchronization between the Chaotic Systems with Mismatching in Parameters

2006 6th World Congress on Intelligent Control and Automation, 2006
In order to realize the synchronization between the chaotic systems with mismatching in parameters, a sliding mode control approach for chaotic synchronization was presented based on high gain state observer. It expanded the mismatching in parameters into a new state, and made full use of the information that can be measured to design high gain state ...
