Patent number: 10833616Abstract: A power management system may include an energy source and a generator driven by a gas turbine engine to output generator power to a common bus. A source power converter is electrically coupled between the energy source and the common bus. A controller circuitry includes an adaptive filter to filter a power signal indicative of power consumption of a variable load on the common bus, and outputs a filtered signal as a load demand signal to the generator. A source demand error signal is also output to control the source power converter to supply power from the energy source to the common bus. The controller circuitry is further configured to automatically adjust the adaptive low pass filter in accordance with the power consumption of the dynamic load and the load demand signal of the generator.Type: GrantFiled: November 22, 2019Date of Patent: November 10, 2020Assignee: Rolls-Royce Marine North America Inc.Inventors: Donald Silverstein, Ainsmar Brown, Ivan Troitsky, James Greg Steinrock
