Introduction: ACservosystemsarewidelyusedinvariousindustrialapplications,includingrobotics,machining,andautomation.Theperformanceofthesesystemsisgreatlyinfluencedbytheircontrolalgorithms.PIDcontrolhasbeenatraditionalmethodusedforACservosystemsduetoitssimplicityandrobustness.However,thefixedparametersofthePIDcontrolleroftenlimititsabilitytoadapttodifferentoperatingconditions,leadingtosuboptimalperformance.Toovercomethislimitation,researchershaveproposedvariousself-tuningalgorithmsforPIDcontrollers,suchasfuzzylogic-basedapproaches. Methodology: Theproposedapproachinthisresearchisthefunction-orientedvariablerangefuzzyPIDself-tuningalgorithm.Thisalgorithmincorporatesafuzzylogic-basedcontrollerwithadaptivetuningcapabilities.Thekeyfeatureofthisalgorithmistheabilitytodynamicallyadjusttherangeofvariationofthecontrollerparametersbasedonthesystem'soperatingconditions.Thisnotonlyimprovestheprecisionandstabilityofthecontrollerbutalsoreducestheovershootandsettlingtimeofthesystem. Tovalidatetheeffectivenessofthefunction-orientedvariablerangefuzzyPIDself-tuningalgorithm,experimentaltestswereconductedusinganACservosystemsetup.Theexperimentalsetupconsistedofamotor,apositionsensor,andacontroller.Thealgorithmwasimplementedusingamicrocontroller,whichreceivedfeedbackfromthesensorandadjustedthecontrollerparametersaccordingly.Variousoperat
