Anti-Saturation Algorithm for a Load Sensing Hydraulic Servo System with Multiple Actuators

A load sensing hydraulic system is widely used to military and commercial mobile applications fur its high running efficiency. Although concept and general control schemes are well known, the poor maneuverability of simultaneous multioperation of actuators still remains to be solved. In this paper, a new control algorithm is proposed to prevent the saturation of the system in such operating conditions, in which the total required flowrate of actuators may exceed the pump supply flowrate. The effectiveness of the proposed algorithm is verified through experiments.
