Research on the control system of the active isolation system

Generally, feedback control is used to reduce the resonances of the isolator and floor feedforward control is added to improve the transmissibility further. The manual iterative method is used to calibrate the gain of the floor feedforward control. This method is time-consumed and not easy to tune. A new calibration method which is based on transmissibility and force mobility is proposed. The test results show that the proposed method works well.
