Consensus control of stochastic multi-agent systems: a survey

Abstract: In this article, we provide a review of the consensus controlproblem for stochastic multi-agent systems (MASs). Recent advancesare surveyed according to the method of occurrence of the stochasticity of the MASs. First, the consensus problem is discussed for MASs, whereinindividual agents are corrupted by random noises, i.e., thedynamics of agents involve stochasticity in process and/ormeasurement equations. Both additive noises and multiplicativenoises are surveyed in detail and special attention is paid to theMASs whose dynamics are governed by Itodifferential equations.Moreover, particular effort is devoted to presenting the latestprogress on the consensus problem for a special type of stochasticMAS with Markovian jump parameters. Subsequently, the relevant research issummarized for MASs with noisy communication environments andstochastic sampling. Further, we provide a systematic review ofthe consensus problems for MASs whose communication topologyvaries randomly in the process of data propagation among agents.Finally, conclusions are drawn and several potential future researchdirections are outlined.

A Single Layer Wideband U-Slot Microstrip Patch Antenna Array

Abstract: The design and measured results of a 2 times 2 microstrip line fed U-slot rectangular antenna array are presented. The U-slot patches and the feeding network are placed on the same layer, resulting in a very simple structure. The advantage of the microstrip line fed U-slot patch is that it is easy to form the array. An impedance bandwidth (VSWR < 2) of 18% ranging from 5.65 GHz to 6.78 GHz is achieved. The radiation performance including radiation pattern, cross polarization, and gain is also satisfactory within this bandwidth. The measured peak gain of the array is 11.5 dBi. The agreement between simulated results and the measurement ones is good. The 2 times 2 array may be used as a module to form larger array.

Bacterial cellulose/TiO2 hybrid nanofibers prepared by the surface hydrolysis method with molecular precision

Abstract: Bacterial cellulose (BC) nanofibers were biosynthesized by Acetobacter xylinum NUST5.2, and displayed a remarkable capability for orienting TiO2 nanoparticle arrays. Large quantities of uniform BC nanofibers coated with TiO2 nanoparticles can be easily prepared by surface hydrolysis with molecular precision, resulting in the formation of uniform and well-defined hybrid nanofiber structures. The mechanism of arraying spherical TiO2 nanoparticles on BC nanofibers and forming well-defined, narrow mesopores are discussed in this paper. The BC/TiO2 hybrid nanofibers were used as photocatalyst for methyl orange degradation under UV irradiation, and they showed higher efficiency than that of the commercial photocatalyst P25.
