In view of the synchronous control problem of vertical loading hydraulic cylinder of super large mining high hydraulic support test stand,a synchronous control strategy based on fuzzy PID is put forward by using Creo-Adams and ANSYS,and constraints are added according to the actual conditions of vertical loading.AMEsim and Matlab/Simulink are used to establish the vertical loading hydraulic system control model,and the multi-field collaborative simulation model of Adams-AMEsim-Simulink machine is built based on the interface technology among the software.The simulation obtains the displacement tracking curve,load change curve,signal control curve and synchronization error curve of loading hydraulic cylinder under fuzzy PID and conventional PID.The results show that compared with the conventional PID algorithm,the system under the fuzzy PID algorithm has the characteristics of faster response speed and higher control accuracy,and the synchronization accuracy error of the hydraulic support is less than 0.1 mm,which meets the use requirements.The research conclusion provides reference for the design of the vertical external loading system of the hydraulic support test bench.
