Dynamic modeling and vibration suppression of the feed drive system

In this paper, a new feed drive model which considers the longitudinal and base vibration models is developed to estimate the elastic deformation. The effect of vibration force feedback to the torque is included. The dynamic model is integrated with the servo drive system. To obtain the dynamic parameter, the peak-picking method is adopted. It is shown from the experimental results that the developed model can predict the elastic deformation quite accurately. Furthermore, by properly designing the acceleration time, one can reduce the base vibration for the feed drive system significantly.
