Introduction:
DCservomotorsarewidelyusedinvariousindustriesduetotheirhighperformance,compactsize,andprecisespeedcontrolcapability.Toachievethedesiredspeedcontrol,anefficientcontrolsystemisessential.Inthispaper,wefocusontheimplementationofaspeedcontrolsystemusingtheP87LPC768microcontroller.
LiteratureReview:
SeveralpreviousstudieshaveaddressedthespeedcontrolofDCservomotors.Traditionalapproachesincludeproportional-integral-derivative(PID)control,adaptivecontrol,andfuzzylogiccontrol.Thesemethodshavetheiradvantagesandlimitationsintermsofcontrolaccuracy,dynamicresponse,andcomplexity.
