This paper proposes the compensation method of vibration noise in the treadmill installing force plate. The treadmill can measure force and moment in walking and running. However, the vibration noise is included the force plate outputs by the belt drive, and the dynamic characteristics of treadmill is increased the effect. The compensation method estimates the error by using the accelerometers installing to force plate in the treadmill. The error is estimated by applying the disturbance observer. We conducted the measurement experiment by no load and belt drive, we obtained the accelerations, and we estimated the inverse models of dynamic characteristics representing by using the pulse transfer function. The error force components were estimated by the models and the accelerations. The compensated forces were calculated by using the force plate outputs and the error force components. The compensated force indicated the results reducing the effect of vibration noises and dynamic characteristics. The proposed method can be used to performance improvement of the treadmill installing force plate.
