Title: ENGINE SYSTEM CONTROL APPARATUS AND ENGINE SYSTEM
Abstract:
The present invention is provided with: a parameter reception unit (47) that receives parameters necessary for acquiring the pressure ratio of a low-pressure compressor and the pressure ratio of a high-pressure compressor; a pressure ratio acquisition unit (49) that acquires the pressure ratio of the low-pressure compressor and the pressure ratio of the high-pressure compressor on the basis of the parameters; an inter-compressor pressure ratio acquisition unit (52) that acquires an inter-compressor pressure ratio obtained by dividing the pressure ratio of the high-pressure compressor by the pressure ratio of the low-pressure compressor; and a control unit (54) that controls an exhaust flowrate adjustment unit (38) so as to set the inter-compressor pressure ratio to a prescribed pressure ratio at which the operation efficiency of an engine system can become optimal.
