Research on the compensation for an electrohydraulic position servo sysem loaded with the alternating spring loads

摘要

An electrohydraulic position servo system loaded with the alternating spring loads is analysed. By using the structure invariance principle, a compensation for the system is discussed. With approximate conditions, an equation of the compensator which is applied to eliminate the effect of the alternating spring loads is put forward. Meantime, the deisgn of the system is discussed briefly.
