GAS SPRING TYPE VIBRATION ISOLATOR AND METHOD OF CONTROLLING THE DEVICE

摘要

A vibration oscillator comprises a spool valve and a pressure differentiator. In order to improve the dynamic characteristics of the spool valve in the dead band, the vibration isolator is so controlled that the feedback value of pressure differential value follows a reference model having such a linearity that the relation between an input voltage and an output flow passes through a zero point to compensate the nonlinearity of the spool valve.
