Transmissibility Reduction for Pneumatic Anti-Vibration Apparatuses Using State of a Central Pattern Generator

Abstract

This paper considers the transmissibility reduction of central pattern generator (CPG) based control system for pneumatic anti-vibration apparatuses (AVAs). This control method is an attenuation method for the flow disturbance, which is the variation of compressed air pressure. A CPG-based controller generates control input, whose frequency is synchronized with the frequency of the flow disturbance. In the proposed method, the parameter in the CPG-based control system is tuned so that the air spring stiffness can be vanished. For this reason, the resonance frequency of the transmissibility can be reduced. It leads to the improvement of transmissibility. The effectiveness of the proposed approach is shown by simulation.
