Abstract: An engine system control apparatus includes a parameter reception unit that receives parameters necessary for acquiring a pressure ratio of the low-pressure compressor and a pressure ratio of the high-pressure compressor, a pressure ratio acquisition unit that acquires the pressure ratio of the low-pressure compressor and the pressure ratio of the high-pressure compressor based on the parameters, an inter-compressor pressure ratio acquisition unit that acquires an inter-compressor pressure ratio obtainable by dividing the pressure ratio of the high-pressure compressor by the pressure ratio of the low-pressure compressor, and a control unit that controls the exhaust gas flowrate adjustment unit such that the inter-compressor pressure ratio becomes a predetermined pressure ratio for optimizing an operation efficiency of the engine system.
