简介：Theproblemofadaptivefuzzycontrolforaclassoflarge-scale,time-delayedsystemswithunknownnonlineardead-zoneisdiscussedhere.Basedontheprincipleofvariablestructurecontrol,adesignschemeofadaptive,decentralized,variablestructurecontrolisproposed.Theapproachremovestheconditionsthatthedead-zoneslopesandboundariesareequalandsymmetric,respectively.Inaddition,itdoesnotrequirethattheassumptionsthatallparametersofthenonlineardead-zonemodelandthelumpeduncertaintyareknownconstants.Theadaptivecompensationtermsoftheapproximationerrorsareadoptedtominimizetheinfluenceofmodelingerrorsandparameterestimationerrors.Bytheoreticalanalysis,theclosed-loopcontrolsystemisprovedtobesemi-globallyuniformlyultimatelybounded,withtrackingerrorsconvergingtozero.Simulationresultsdemonstratetheeffectivenessoftheapproach.
