Embodiment 2
[0091] In the second aspect, see Figure 5 , this embodiment also provides a control method based on any of the above-mentioned intelligent active control type high-pressure pipeline pressure pulsation damping devices, including:
[0092] S1. Using an input pressure sensor to obtain pressure pulsation information of a high-pressure pipeline.
[0093] S2. The information conversion device converts the vibration information into corresponding data information.
[0094] S3. The control unit obtains information on the vibration frequency, amplitude and phase of the pressure pulsation of the high-pressure pipeline according to the data information, and finally determines the vibration of the high-pressure pipeline through data processing and analysis of the pressure pulsation data and the model of the high-pressure pipeline For frequency, magnitude and phase data information, see Figure 8 . An incremental PID control algorithm is used to process the data information, a control ...
