A passive electrohydraulic force control system (PEFC system for short) is used to simutlate an arbitrary load force. It is linked with a loaded equipment in working. Hence, when the load force is exerted in the same direction as that of the motion of the loaded equipment,we define the PEFC system working condition as the negative operation, when their directions are different, we define the PEFC system working condition as the positive operation.The motion of the loaded equip-
It is linked with a loaded equipment in working. Therefore, when the load force is exerted in the same direction as that that of the motion of the loaded equipment, we define the PEFC system working condition as the negative operation, when their directions are different, we define the PEFC system working condition as the positive operation.
