When a motion control system tracks a fast moving target, the over-tune is the main part of the dynamic tracking error. The speed delay compensation may be used to decrease the error but the stability is sacrificed. We put forward the Differential Position Feedback control, and discuss its effects and control mechanism through simulation. With transfer function identification, we find that the Differential Position Feedback(DPF) control is based on internal model principle. The simulation results show that DPF can improve the tracking ability for the fast moving target but lower the tracking precision at low frequency region. If it is combined with the dynamic integral control, better tracking precision can be obtained.
