Abstract：

It was introduced electro hydraulic servo system composition and working principle of 60 MN hydraulic press. Considering the complexity of load change in the electro hydraulic servo system, based on the analysis of load characteristics, the active disturbance rejection control (ADRC) strategy was put forward to improve its controllability and robustness. Then active disturbance rejection controller was analyzed and designed. Finally, the whole simulation model of electro hydraulic servo control system was established by MATLAB/Simulink, and the effect of ADRC was studied under different load changing frequencyies. The study shows that compared with the PID controller, not only the response speed of electro-hydraulic servo system is improved and the overshoot of system is effectively reduced, but also robustness of system is enhanced.
