Abstract
Provided is a system for electro-hydraulic control of hydraulic pipeline rupture protection based on differential pressure feedback, which relates to the field of hydraulic control technology. The system comprises a hydraulic actuation system and a controller system. The controller system comprises a differential pressure feedback loop and a flow rate diagnostic loop. The differential pressure feedback loop is configured to obtain a flow rate signal within a hydraulic pipeline and determine a proportional signal. The flow rate diagnostic loop is configured to receive the proportional signal, and in response to determining that a duration for which the proportional signal remains outside a threshold range reaches a preset safety duration, cut off an actuating end of the hydraulic actuation system to achieve pipeline rupture protection.
