VIBRATIONAL FLUID MOVER ACTIVE CONTROLLER

摘要

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.

1. A vibrational fluid mover comprising:
a housing defining a chamber, the housing having at least one orifice formed therein; at least one actuator element positioned on the housing that moves in a time harmonic fashion responsive to a form of wave shape voltage applied thereto, such that a volume of the chamber increases and decreases to entrain fluid into the chamber and eject a jet of fluid out from the at least one orifice; and a control system operably connected to the at least one actuator element to cause the form of wave shape voltage to be provided thereto so as to actively control the time harmonic movement of the at least one actuator element, wherein 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 to the at least one actuator element;monitor operation of the vibrational fluid mover during continued operation thereof at the target voltage and frequency;identify a deviation of the operational parameter from the baseline value during the continued operation thereof at the target voltage and frequency; andmodify the voltage and frequency provided to the at least one actuator element based on the identified deviation of the operational parameter from the baseline value.
