A method and an apparatus for controlling an engine system in an engine characteristic test capable of accurately performing controlling operations. In the apparatus rotational speed, axial torque, and operational energy of the engine as well as rotational speed of a dynamometer are detected. The operational energy of the engine is controlled by an engine controller. A predetermined rotational speed of the engine and a predetermined axial torque of the dynamometer are set. A first difference between the predetermined rotational speed and the detected rotational speed of the dynamometer as well as a second difference between the predetermined axial torque and the detected axial torque of the engine are calculated. Controlled gains based on a predetermined mathematical model corresponding to the engine system are calculated from the detected operational energy, the detected axial torque and the detected rotational speed of the engine and the detected rotational speed of the dynamometer. Manipulated variables to perform at least integral and proportional operations are calculated from the control gains; the detected operational energy and the detected axial torque of the engine; The calculated first difference and the calculated second difference. the engine controller and the dynamometer are controlled by a system controller according to the calculated manipulated variable.
