STABTLIZATTON OF AN ELECTROHYDRAULIC SERVO USING DYNAMIC PRESSURE FEEDBACK

S K NAIR, S N RAO

Abstract


This paper discusses the advantages and disadvantages of different methods of stabilization of poorly damped electrohydraulic servos. Using linear analysis, il is shown that the technique of dynamic pressure feedback can be employed to stabilize the servo without deteriorating its performance in other respects. An example is worked out to illustrate the design procedure.

Keywords
