Abstract：Inordertoimprovethestabilityof theclosed-loopsystemandreduce theenergyconsumptionof thesensor node， amethodofpoweroptimizationschedulingwithtime-varyingconvergenceastheperformanceindexisstudiedfortheclosed-loop discrete networkedsystem.According tothe packet losstatusofthenetwork transmission process and thequantizedoutput fedbackdata，thecontrolunitbasedonthestateobserverisdesigned.Aquantitativeencodingstrategyisdesignedtorealizethe datatransmissonof thesystemunder theconstraintof networkbandwidth.Fromthenewperspectiveof takingthetime-varying convergencerateandnode energyconsumptionas the system performanceoptimizationindex，thepowerschedulingalgorithmis designed to minimize the givenperformanceindex under the premiseof ensuring the exponential convergencein the meaning of the system mean，so as toachievethepurpose of improving thesystem convergencespeed andsaving energyconsumption.The effectiveness of the proposed method isverified by the example simulation.
