Study on distributed active control of fluid pulsation in hydraulic piping

  • Periodic fluid pulsation in aeroplane hydraulic piping could induce fluid-construction vibration and lead to fatigue damage. It is impossible to find the error sensor′s optimization location because of the pressure standing wave, and the pulsation attenuation effect is not perfect when adopting pulsation attenuation at single point. For this reason, a distributed active control method of fluid pulsation was presented. To avoid stationary point in all aviation states, several fluid pulsation actuators and error pressure sensors were placed along the piping. The second fluid pulsation produced by actuators can counteract the primary pulsation brought by aviation piston pump and make the mean pulsation of whole piping minimum when adopting adaptive feedforward control and the filtered-X least mean square( LMS) algorithm. In order to validate the vibration attenuation effect, a test platform was designed and built. Experiment results show that the distributed pulsation active control method adopted in the paper can attenuate the fluid pulsation effectively and the pulsation attenuation is over 10 dB.
