With the development of the aircraft hydraulic power supply system towards high pressure and large load, Fluid-borne vibration in piping systems leads to serious problems. Because of pump’s periodic flow pulsation and fluid-structure interaction, mechanical fatigue can readily take place. Traditionally, passive pulsation dampers have been used to reduce fluid pulsation of high frequencies, but the application of such passive devices is limited in low frequency conditions because of their bulk volumes or poor performances. This paper presented a distributed active control method using piezoelectric direct drive servovalve to reduce the fluid pulsation in pipeline systems. The idea
