基于分数阶滑模观测器的PMSM分数阶积分滑模控制（英文） Title:Fractional-OrderSliding-ModeObserver-BasedFractional-OrderIntegralSliding-ModeControlforPMSM Abstract:Inrecentyears,permanentmagnetsynchronousmotors(PMSMs)havegainedsignificantattentioninvariousindustrialapplicationsduetotheirhighefficiencyanddynamicresponse.ToenhancetheperformanceofPMSMs,advancedcontroltechniqueshavebeendeveloped.Thispaperproposesanovelcontrolstrategy,namelytheFractional-OrderSliding-ModeObserver-BasedFractional-OrderIntegralSliding-ModeControl(FO-SMO-FISM)forPMSMs.TheFO-SMO-FISMcombinesthebenefitsoffractional-ordercontrol,sliding-modeobserver(SMO),andintegralsliding-modecontrol(ISM)toachievesuperiortrackingaccuracyandrobustness.
