1. 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.
