A Double-channel iterative NFXLMS algorithm used in Horizontal Vibration Isolation

In order to solve the multi-directional coupling problem of the vibration isolation platform caused by the partial load, a novel adaptive feed-forward control method is proposed. In the paper, we mainly used the Double-channel iterative NFXLMS algorithm to get a better performance of vibration isolation. And the control system is not sensitive to the error from the model identification. Then the algorithm is validated by the simulation and experiments. The results show that the performance of the vibration isolation system is mainly improved in the low frequency.
