An independent import and export control was developed, based on variable speed load sensitivity at mode switching, to address the issues of high efficiency but insufficient control precision of the pump control position system and rapid reaction but significant energy loss of the valve control position system. A control strategy is designed for stagnant load conditions with large energy loss in construction machinery. First, a mathematical model of the variable speed load-sensitive independent position control system for the import and export was established, according to the above control principle. Second, the test platform and AMESim-MATLAB simulation model based on the load sensing system of the loaded cylinder and the position control system of the empty cylinder were established and analyzed. Then, sinusoidal and random signals are added to the built system model to simulate varying loads, and the control and pressure of system position accuracy were analyzed under variable load. Finally, the built system was analyzed and compared with a constant current valve control system, traditional load-sensing valve control system, and traditional pump control system. The results show that the designed variable speed load-sensitive pressure controller has a good control effect on system pressure; the position control performance and energy saving effect of the load-sensitive inlet and outlet independent control system with servo motor-driven double-acting vane pump as the power source are higher than those of traditional pump control and valve control systems, which saves the energy by 10.11% over the traditional pump control system.
