THE OBJECTIVE OF THIS PROJECT IS TO GENERATE A GENERALIZED CONTROL SCHEME THAT CAN BE USED TO ADVISE THE OPERATION OF SCO2 COMPRESSORS EMPLOYING VARIABLE INLET GUIDE VANES (IGVS). IT IS EXPECTED THAT INCORPORATION OF IGVS TO SCO2 COMPRESSORS OPERATING NEAR THE SUPERCRITICAL DOME CAN IMPROVE OFF-DESIGN EFFICIENCY BY UP TO 20%.
