Zusammenfassung:	Systems and methods for controlling heating of a hydrocarbon medium using a signal generator and a load having frequency and time dependent impedance. A desired heating life cycle is determined. A current state is determined using a model of the medium and the load. A desired operational state is determined from the current operational state and the desired heating life cycle. The desired operational state is selected to maximize a fit between the desired operational state and the desired heating life cycle. Desired signal generator control settings are determined for the signal generator in order to achieve the desired operational state. An output signal is generated using the signal generator by applying the at least one desired signal generator control setting to the signal generator. The output signal is defined to excite the load and thereby heat the hydrocarbon medium.
