A unified appr.ach to output synchr.nization of heter.geneous multi-agent systems via L2-gain design

引用

作者： Shan Zuo Yongduan Song Hamidr.za Modar.s Fr.nk L. lewis Ali Davoudi School of Automation Engineer.ng University of Electronic Science and Technology of China Chengdu Sichuan China The Univer.ity of Texas at Ar.ington r.sear.h Institute Fort Worth U.S.A.

In this paper. a unified design pr.cedur. is given for.output synchr.nization of heter.geneous multi-agent systems （MAS） on communication gr.ph topologies, using r.lative output measur.ments fr.m neighbor.. Thr.e differ.nt contr.l pr.tocols, namely, full-state feedback, static output-feedback, and dynamic output-feedback, ar. designed for.output synchr.nization. It is seen that a unified design pr.cedur. for.heter.geneous MAS can be given by for.ulation and solution of a suitable local L2-gain design pr.blem. Sufficient conditions ar. developed in ter.s of stabilizing the local agents＇ dynamics, satisfying a cer.ain small-gain cr.ter.on, and solving the output r.gulator.equations. Local design pr.cedur.s ar. pr.sented for.each agent to guar.ntee that these sufficient conditions ar. satisfied. The pr.posed contr.l pr.tocols r.quir. only one copy of the leader.s dynamics in the compensator. r.gar.less of the dimensions of the outputs. This r.sults in lower.dimensional compensator. for.systems with high-or.er.outputs, compar.d to the p-copy inter.al model appr.ach. All thr.e pr.posed contr.l pr.tocols ar. ver.fied using numer.cal simulations.

The r.les of Differ.nt CLE Domains in Ar.bidopsis CLE Polypeptide Activity and Functional Specificity

引用

Molecular.Plant 2010年第4期3卷 760-772页

作者： Ling Meng Kenneth C. r.th Jennifer.C. Fletcher.lewis Feldman Depar.ment of Plant and Micr.bial Biology 111 Koshland Hall University of California Berkeley CA 94720-3102 USA Plant Gene Expr.ssion Center USDA-UC Berkeley 800 Buchanan Street Albany CA 94710 USA

The CLE （CLVATA3/ESr.r.lated） family of plant polypeptide signaling molecules shar.s a conser.ed 14-aminoacid （aa） motif, designated the CLE motif, which r.cent studies suggest is sufficient for.CLE function in vitr.. In this study, we r.por. that Ar.bidopsis CLE pr.teins can function in a tissue-specific manner.and confir. some CLE factor. can act thr.ugh differ.nt r.ceptor.. Using domain swapping, we show for.the fir.t time that the CLE motif likely deter.ines much of the functional tissue-specificity of the pr.teins in planta. However. we also pr.vide evidence in suppor. of the new view that sequences outside the CLE motif （14 aa） contr.bute to CLE function and functional specificity in vivo. Additionally, we r.por. that deletion of the putative signal peptide fr.m differ.nt CLE pr.teins completely inactivates CLE function in vivo, wher.as exchanging the CLE signal peptides with a conventional signal peptide fr.m a r.ce glycine-r.ch cell wall pr.tein also influences CLE function. We thus pr.pose that the CLE motif itself deter.ines its functional tissue-specificity by dic- tating the dir.ct r.cognition and inter.ction of each CLE peptide with its optimal r.ceptor.s）, wher.as the r.ceptor.s） may be available in a tissue-specific manner. On the other.hand, the sequences outside the CLE motif may influence CLE function by affecting the pr.cessing of CLE peptides, r.sulting in a change in the availability and/or.abundance of CLE peptides in specific tissues and/or.cells.
