Research status and prospect of pulsating active control of hydraulic pipeline

In order to solve the problem that the traditional muffler in the field of low-frequency pulsation noise control of submarine hydraulic system is easily interfered by external factors and does not have adaptive ability. Scholars from all over the world have carried out research on the active control of pulsation noise of liquid pipelines. This paper first explains the principle of active control of hydraulic line pulsation and active noise. Sound control technology, from the aspects of software and hardware to sort out and review the noise reduction principle and research progress of the control system, analyze the advantages and disadvantages one by one. And the future research direction and application prospect are prospected.
