Abstract
To avoid rework in the automobile engine calibration and verification process, engine test bench is expected to improve precision of standard test for in fuel consumption. In this paper, the control system that switches conventional feedback control to feedforward control is proposed to the acceleration change phase of in order to satisfy the required following precision to the reference vehicle speed. Feedforward control input is calculated as the driving force of the automobile by giving final-state control on the controlled object model based on the equivalent inertial mass and running resistance. It is seen from comparison with experimental results on engine test bench that highly precise fuel consumption test can be realized.
