According to the structure of servomechanism on HD2se-ries pump, their functions have been analyzed. The structure and control process of constant power valve are mainly discussed.
The parameter identification of joining stiffness of rudder hydraulic servomechanism can be done by using the direct method of characteristic equation anti problem.
