Claim 7:
8. A hydraulic system comprising:
the control device according to claim 1; and
the valve device including at least one electromagnetic proportional valve and a spool valve, wherein:
the spool valve includes a spool that is the valve body;
the spool travels according to a pilot pressure acting on the spool;
the at least one electromagnetic proportional valve outputs the pilot pressure acting on the spool; and
when the flow state determination unit determines that the flow is not in the transient flow state, the valve body control unit controls the movement of the valve body by causing the at least one electromagnetic proportional valve to output the pilot pressure that corresponds to the opening command, and when the flow state determination unit determines that the flow is in the transient flow state, the valve body control unit controls the movement of the valve body by causing the at least one electromagnetic proportional valve to output the pilot pressure that corresponds to the target flow rate value.
