Urgency of the research. DCmotorsare very important andtherefore greatattention is paidto theirdevelopment and production. DCmotorsareusedwherever a wide rangeof speedcontrol is required,orwherestartingconditions aredifficult.They are characterized by simple speed controllability andreliability.Target setting. The article dealswith the analysisof a DCmotorwith a focusonspeedcontrolusingthe design of a PI controller. Matlab/Simulinksoftware is usedforsimulation.Actual scientific researches and issues analysis. The PI controller is themostcommoncombinedcontrollerbecauseit has an almostuniversaluse. In a closedloopcontrolsystem, it eliminates permanentcontroldeviation andimprovesstability.At the beginning of thecontrol, theinfluenceof theproportional termprevails,with increasing time theinfluenceof the inte-grationtermprevails.Uninvestigated parts of general matters defining.Another taskwillbe to verify theproposedPI controllerona realmotor.The research objective. The main aimwasto create controlof a DCmotorusing a PI controller. Theproposedcontrolsystemregulates themotor speedwithzerocontroldeviation.The statement of basic materials. It is a typeof electric motorpowered by directcurrent. The main advantagesincludeversatility andsimplicity.Conclusions. The aimof the articlewasto create a mathematicalmodel,which is the mainbuildingblockforsimulationsin a computerenvironment. Basedon the available parameters of the selected DCmotor, this mathematicalmodel and its functionalityweresimulated.Subsequently, the PI controller is designed and its simulationwith different loadcharacteristics.
