| Abstract: | To improve the axial pressure control precision of the friction welding process, mathematical analysis to the friction welding electro-hydraulic proportional axial pressure control system was done. Based on the characteristics of the system, the electro-hydraulic proportional axial pressure control system mathematical model was established, and Simulink simulation analysis was carried out at the same time. The PID control algorithm was adopted to correct the system,so the quickness, stability and accuracy of the control system were improved. |
