Analysis on Composite Action Control Strategy of Separate Meter-in Separate Meter-out Control System

摘要

Based on the shortcomings of traditional multi actuator composite action on its coordination and load adaptability, this paper has put forward a hydraulic system model where separate meter-in separate meter-out controls the multi actuator, according to different action working conditions of actuator, it has provided a composite control strategy based on pressure flow, and through AMEsim and MATLAB, it has established the composite action hydraulic transmission model of double-actuator system and simulation model of control system, and then conducted co-simulation to verify the designed controller's good coordination and load adaptability to the separate meter-in and separate meter-out control system under different composite action working conditions.
