Abstract
A controller may use energy packets to control a prime mover of a machine. The controller may include an energy packet measurement control to calculate energy packets, perform post-processing actions on the energy packets to generate processed energy packets, and convert the processed energy packets into a fuel valve reference. Post-processing may include a calibration correction to remove measurement artifacts.
Claims9
A control system for a prime mover of a monitored machine, the control system comprising:
- an energy packet control to:
- calculate energy packets associated with the monitored machine,
- perform post-processing actions on the energy packets to generate processed energy packets, and
- convert the processed energy packets into a fuel valve reference;
- and
- a frequency control to generate frequency error corrections and power setpoint adjustments for the monitored machine,
- wherein the energy packet control updates the fuel valve reference faster than the frequency control generates the frequency error corrections and the power setpoint adjustments;
- an adder circuit in communication with the energy packet control and the frequency control, the adder circuit configured to add the fuel valve reference and the frequency error corrections to determine a prime mover power reference;
- and\
- a communications interface configured to provide the prime mover power reference to a fuel valve control mechanism of the monitored machine such that a fuel flow rate of fuel from a fuel source is controlled in accord with the prime mover reference.
A device to control a prime mover of a monitored machine, the device comprising:
- an energy packet measurement feedback loop comprising an energy packet control to calculate energy packets associated with the monitored machine, perform post-processing actions on the energy packets to generate processed energy packets, and convert the processed energy packets into a fuel valve reference;\
- a frequency control feedback loop comprising:
- a power measurement sensor to obtain a power measurement of the monitored machine, and
- a frequency control in communication with a state complement filter, the frequency control to apply a droop factor to a blended power feedback and output a frequency power feedback;
- and
- a fuel valve calculator in communication with an energy packet measurement control and the frequency control, the fuel valve calculator to add the fuel valve reference and the frequency power feedback to determine a prime mover power reference, and provide the prime mover power reference to a fuel valve control of the monitored machine such that a fuel flow rate of fuel from a fuel source is controlled in accord with the prime mover reference;
- wherein the energy packet control provides the fuel valve reference faster than the frequency control outputs the frequency power feedback and the fuel valve calculator provides the prime mover power reference.
