Abstract: Active vibration control engine mounts are installed in
automobiles to reduce vibration and improve ride quality. Previous control
methods could be only applied when the phase difference is between -π/2
and π/2. In this paper, a new method that can be used at any phase
difference, and that uses step delays so that pre-modelling of the device
becomes unnecessary, is proposed. The effectiveness of the method is
demonstrated through experimental results.
