The invention relates to the technical field of hydraulic
automatic control, in particular to an automatic regulating
system and method for a hydraulic
butterfly valve, and the
system comprises a hydraulic
power regulation and control module, an opening degree detection and correction module, a flow dynamic matching module, a
pressure balance optimization module and an execution mechanism self-matching regulation module. According to the method, the pressure and flow characteristics are extracted through the operation parameters of the
hydraulic pump, the adaptability and accuracy of hydraulic transmission are effectively improved, in
butterfly valve adjustment execution, the timeliness of
adjustment action and target consistency are enhanced by analyzing opening deviation and response aging quantization error accumulation in real time, accurate allocation of flow and pressure resources is achieved, and the adjustment efficiency is improved. In the
dynamic control stage, the output matching sequence is continuously adjusted according to the corresponding relation between the unsatisfied requirement and the remaining capacity,
response delay and adjustment deviation are remarkably reduced, and therefore the continuity, coordination and adjustment precision of
butterfly valve control are improved, and stable operation of a hydraulic
system under variable working conditions is effectively guaranteed.
