In the vehicle development, it is important to shorten the development period of the powertrain components such as transmission, torque converter. In order to simulate real road loads of the powertrain components, it is necessary that the dynamometer of the drivetrain bench emulates the moment of inertia of a tire. To emulate the desired moment of inertia, controller parameters are calculated based on system identification in conventional scheme. In the aforementioned control scheme, high accuracy of system identification is required. This paper proposes a data-oriented control system whose controller parameters are directly calculated without system identification. In the proposed scheme, the fictitious exogenous signal is calculated using closed-loop data, and controller parameters and system parameters are simultaneously obtained. Finally, the effectiveness of the proposed scheme is verified by using a numerical example.
