When the tractor transports the heavy hitch equipment, the hydraulic cylinder pressure impact of the electro-hydraulic hitch is severe, and the tractor will produce large pitching movement. The dynamic pressure feedback correction was added to the position control system to increase the system damping ratio to suppress the system pressure fluctuation. The output signal of the pressure sensor was collected and input to the system through the controller differentiator, which could increase the damping ratio of the system without affecting the dynamic stiffness of the system. The kinematics model of tractor electro-hydraulic hitch was established, and the angle transmission ratio of each link was analyzed. The dynamic model of the tractor hitch system was established, and the load force of the hydraulic cylinder was solved by programming with Matlab. The hydraulic system model was established, the damping ratio of the hydraulic system after adding dynamic pressure feedback correction link was analyzed, and the confirmation method of dynamic pressure feedback parameters was given. Matlab/Simulink was used to simulate the model. The simulation results showed that during the lifting process of the hydraulic system, the pressure was changed greatly, and the maximum pressure reached 5.8MPa. After correction, the pressure fluctuation of the electro-hydraulic hitch system was small, and the maximum pressure was only 4.0MPa. When the interference force impacted the hydraulic system, the pressure fluctuation range of the original hydraulic pressure system was 2.7MPa. In comparison, the position control pressure fluctuation range after using dynamic pressure feedback correction was 1.1MPa. Therefore, the damping ratio of the system could be effectively improved, and the pressure fluctuation could be suppressed by the method. The test platform was built. The test results showed that the maximum lifting pressure of the uncorrected system was 4.6MPa and the pressure oscillation was decreased. In contrast, the maximum pressure of the corrected system was only 3.8MPa, and the pressure was relatively gentle. In the impact interference test, the maximum pressure of the original system reached 6.5MPa, and the pressure fluctuation range was 6MPa. In contrast, the corrected maximum pressure was only 4.6MPa, and the pressure fluctuation range was 4.2MPa. Compared with the locking condition of the original system, the pressure fluctuation range was reduced by 30%. The results showed that the proposed dynamic pressure feedback correction method of the tractor electro-hydraulic hitch can well restrain the pressure fluctuation of the hydraulic cylinder of the tractor electro-hydraulic hitch, protect the agricultural machinery, reduce the pitching movement and improve the comfort of the driver.
