The increased stiffness shifted the modes of the structure beyond the operating frequency range. The structural dynamic modification model with linearized piezo stack actuator hysteresis showed better performance compared to the original-active suspended handle model. A proportional feedback gain (P) step-up method is used for counter voltage to the piezo stack actuator in a real-time active vibration control system. The effective frequency range of isolation, with transmissibility smaller than unity, was expanded from 250\u2013450\u2009Hz to 200\u2013510\u2009Hz, and the anti-node transmissibility was lowered from \u221218 to \u221226\u2009dB. Laboratory testing using a die grinder with a nominal operating speed of 25,000\u2009r\/min showed that the structural dynamic modification-active suspended handle reduced vibration transmissibility by up to 96%.
