Abstract
Provided is a fluid control apparatus capable of setting, to a value as close as possible to an opening start voltage, an initial applied voltage applied when controlling a control valve so that a measured amount becomes a set amount from a fully closed state and capable of preventing occurrence of large overshoot while increasing a response speed. A valve controller inputs a voltage command for setting an initial driving voltage to be applied to a control valve to a voltage generation circuit in a case where the control valve is changed from a fully closed state to a predetermined opening degree, and includes a drive history storage unit that stores therein drive history information of the control valve. The controller is configured to change a value of the initial driving voltage in accordance with the drive history information.
