Summary:

This paper deals with the optimum design of the stiffness and damping coefficients of the spring and dashpot used in the feedback loop of a hydraulic servovalve, to attain minimum surge pressure during the stop and reverse operations. The proportional element of the feedback represented by the lever ratio is predefined. The state space equations are derived and two objective functions based on relative and absolute pressure rise are minimized. The applied minimization technique is based on a modified gradient method.The results show a better performance and less shocks due to the optimum design of that dynamic parameters
