Gas turbine engine generator power management control system

A method comprising:

• monitoring a power signal indicative of a load on a common bus, the load comprising a pulse load;
• filtering the power signal with an adaptive filter to generate a filtered power signal;
• identifying a relatively constant part of the power signal;
• dynamically adjusting the adaptive filter in accordance with the identified relatively constant part of the power signal;
• generating a demand setpoint for a gas turbine engine rotatably driving a generator based on the filtered power signal provided by the dynamically adjusted adaptive filter, the gas turbine engine rotatably driving the generator to produce generator output power for a portion of the pulse load in accordance with the demand setpoint;
• generating a power output setpoint for a source power converter in accordance with the filtered power signal provided by the dynamically adjusted adaptive filter;
• and
• supplying source power to the common bus from a power source via the source power converter, the source power supplied to a remaining portion of the pulse load according to the power output setpoint.

A system comprising:

• an energy source;
• a generator rotatably driven by a gas turbine engine to output generator power to a common bus;
• a source power converter electrically coupled between the energy source and the common bus;
• and
• a controller circuitry comprising an adaptive filter configured to filter a power signal indicative of power consumption of a variable load on the common bus, and output a filtered signal as a load demand signal to the generator,
• the controller circuitry further configured to output a source demand error signal to control the source power converter to supply power from the energy source to the common bus,
• wherein the source demand error signal is representative of a difference between the filtered signal and power consumption of the dynamic load;
• the controller circuitry further configured to dynamically adjust the adaptive low pass filter in accordance with the power consumption of the dynamic load and the load demand signal of the generator.
