According to the characteristics of 400 kN / 800 kN.m rotary control system of forging manipulator, the modeling and simulation of the rotary hydraulic servo control system of forging manipulator are carried out by using MATLAB / Simulink and AMESim co-simulation technology. The simulation results show that the control system based on the fuzzy control algorithm can automatically adapt to the on-site working environment of the forging manipulator and dynamically output various adjustment parameters of the PID controller. Compared with the control system based on the ordinary PID algorithm, the control system of the control system Great adaptability, quick response, improved real-time control system, more stable operation of forging manipulator and 10% ~ 20% control precision. The smaller the load is, the higher the precision is.
