Claim:
1. A method of finding an operating frequency for a drive signal to a transmit coil in a wireless power transfer system (WPTS), said method comprising: applying a pseudo-random signal to the transmit coil; while the pseudo-random signal is being applied to the transmit coil, recording one or more signals produced within the WPTS in response to the applied pseudo-random signal; by using the one or more recorded signals, generating a dynamic system model for some aspect of the WPTS; and conducting a search for an optimum frequency for the drive signal, wherein conducting the search comprises repeatedly using the generated dynamic system model to simulate a response to the drive signal while varying the operating frequency of the drive signal until the optimum frequency is found.
