For the synchronization motion control of hydraulic synchronization control system with double cylinders, the system dynamic characteristics under the action of two typical load forces of ramp partial load force with linear uniformly varying and index partial load force with nonlinearly varying, as well as two complex load forces of nonlinear sinusoidal partial load force with large-amplitude and linear triangular full-wave load force were studied, and the global mathematical model of hydraulic synchronization control system with double cylinders was built by mechanism modelling. Based on the Matlab/Simulink software environment, the whole simulation model of hydraulic synchronization control system with double cylinders was built, and the main parameters of the system were set up. Then, the changes of the system under several typical load forces and complex load forces were simulated and researched, and the dynamic characteristics of this system were obtained under several typical loading forces to provide reference for improving the control performance of hydraulic synchronization control system.
