Apparatus and method for controlling thruster valve

摘要

When the operation of an electromagnetic thruster valve disposed in a fluid passage for establishing the connection between a gas tank and a thruster unit for jetting gas filled in the gas tank is controlled to follow a thrust command, rise time of thrust at certain thrust is measured based on a state of the operation of the electromagnetic thruster valve. Then, the measured value and a predetermined delay value are subject to a comparison. The obtained difference is used as previous delay time to correct delay time of operation control of the electromagnetic thruster valve with respect to a next thrust command when the operation of the electromagnetic valve is controlled.
