1. A wireless energy transfer system comprising:

  • an energy transmitter comprising a transmitter-impedance matching network (IMN), the transmitter configured to perform operations comprising;

    performing a first comparison between a characteristic of a power of the transmitter and a target power; and

    adjusting, based on the first comparison, a reactance of the transmitter-IMN to adjust the power of the transmitter; and

    an energy receiver comprising a receiver-IMN, the receiver configured to perform operations comprising;

    determining an efficiency of the wireless energy transfer system at a second time based on power data from the transmitter;

    performing a second comparison between the efficiency at the second time and an efficiency of the wireless energy transfer system at a first time, the first time being prior to the second time; and

    adjusting, based on the second comparison, a reactance of the receiver-IMN.
