The vibrations problem of fluid power supply and piping systems in aircraft is discussed,and presented a vibration active control method to reduce the vibrations of fluid power supply and piping systems. The multi-layer PZT is taken as the driver which is of characteristics of large force output, high frequency bandwith and small volume. The auto optimum control method is adopted, which can adjust control parameters at any time to aganist the disturbance.The simulation and experiment result prove that the scheme is efficient. All of the work is benefit to the vibration control in hydraulic system.
