Abstract
A vibrational fluid mover includes a housing having at least one actuator element positioned thereon that vibrates responsive to a wave shape voltage applied thereto, such that a volume of a chamber in the housing increases and decreases to entrain and eject fluid into/out from the chamber. A control system is operably connected to the actuator element to cause the voltage to be provided thereto so as to actively control the movement of the actuator element. The control system is programmed to set a baseline value for an operational parameter of the vibrational fluid mover generated responsive to a target voltage and frequency being provided, monitor operation of the vibrational fluid mover during operation at the target voltage and frequency, identify a deviation of the operational parameter from the baseline value, and modify the voltage and frequency provided to the actuator element based on any deviation of the operational parameter.
