Abstract
A pump control device controls a pump including a vibration actuator for vibrating a vibrating body due to electromagnetic drive caused by electrical current supply to coils, a sealed chamber which includes a movable wall which can be displaced by vibration of the vibrating body so that fluid can be suctioned into an inside of the sealed chamber or discharged from the inside of the sealed chamber, and a discharge portion for communicating the fluid between the sealed chamber and a tank to increase pressure of the fluid. The pump control device contains an obtaining part for obtaining pressure value information, and a control unit for controlling a drive frequency of an electrical current to be supplied to the coils based on the obtained pressure value information.
