Abstract
A method and apparatus for tuning the operational frequency of an electrical generator coupled to a time-varying load is described. One illustrative embodiment rapidly calculates an error (reflection coefficient magnitude) at the current operational frequency of the electrical generator; adjusts the frequency of the electrical generator by an initial step size so; rapidly calculates a second error; and if the magnitude of the second error is smaller than the magnitude of the first error, then the step size is increased and the frequency is adjusted by the increased step size.
