This paper gives out a simple and practical method of designing electrohydraulicservosystem by using PID plus output feedback to make arbitrary configuration of pole-zero in closed-loop system.
The structure and the principle of the hydraulic pull-bending machine based on electrohydraulicservosystem were introduced. And the design of the stretching force in the system was mainly addressed.
