Abstract
A jet generator is controlled by providing an input signal at a variable frequency to the jet generator and to a simulated electrical load of the jet generator, measuring a difference in signals between the jet generator and the simulated electrical load to identify an optimum flow of a jet generated by the jet generator, and tuning the frequency of the input signal to maintain the jet at the optimum flow.

An apparatus comprising:
- a power supply for providing an input signal at a variable frequency to a jet generator effecting a synthetic jet and to a simulated electrical load of the jet generator;
- detection circuitry for measuring a difference in signals between the jet generator and the simulated electrical load to effect an optimum flow of the synthetic jet;
- and
- adjustment circuitry for tuning the variable frequency of the power supply to maintain the synthetic jet at the optimum flow.
