PROBLEM TO BE SOLVED: To monitor operating conditions of a synthetic jet actuator.SOLUTION: A vibrational fluid mover includes a housing having an actuator element, and the actuator element vibrates in response to a wave shape voltage applied to the actuator element such that a volume of a chamber in the housing increases and decreases to incorporate fluid in the chamber and discharge the fluid from the chamber. A control system is operably connected to the actuator element to actively control the operation of the actuator element and cause the voltage to be provided to the actuator element. The control system is programmed to set a baseline value for an operational parameter of the vibrational fluid mover generated in response 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 on the basis of any deviation of the operational parameter. |
