PROBLEM TO BE SOLVED: To provide a control device of an engine which avoids control interference by mutually cooperating control of an EGR valve and control of a variable nozzle and improves controllability effectively.SOLUTION: A control device of an engine includes: an EGR system 40 containing an EGR valve 42 provided on a channel 41 connecting an exhaust system with an intake system; and a variable displacement supercharger 20 containing a variable nozzle 20c provided in a turbine 20b driven by exhaust. The control device further includes: an intake pressure sensor 31 for detecting an intake pressure of the engine 10; an intake air flow sensor 30 for detecting an intake air flow of the engine 10; and sliding mode control units 51 to 55 for outputting controlled variables to an opening of the EGR valve 42 and an opening of the variable nozzle 20c by sliding mode control on the basis of values detected by the intake pressure sensor 31 and the intake air flow sensor 30. |
