1. A system, comprising:
- at least one engine operable to generate a power output in response at least in part to an operator power request and sensed parameters from a sensor;
an engine control subsystem configured to control operation of the at least one engine;
an electrical power subsystem including at least one electrical power device that is operable to demand electric power during operation of the at least one engine; and
a controller connected to the engine control subsystem and to the electrical power subsystem with a system data bus, wherein the controller is configured to determine an anticipatory electric power demand of the at least one electrical device based on current operating conditions and provide control signals to the engine control subsystem to control the at least one engine to generate the power output to meet a total power demand, wherein the total power demand includes at least the anticipatory electric power demand and a nominal power demand based at least in part on the operator power request, and wherein the controller is configured to initiate compensation for the anticipatory electric power demand prior to the at least one engine receiving an increased demand for power output.

10. A system comprising:
-
at least one control system including a controller connected via a first data bus to at least one condition sensor, wherein the controller is configured to determine a nominal power demand at least one engine according to parameters sensed by the condition sensor and an operator power request; an engine control subsystem connected to the controller with a system data bus, wherein the engine control system is configured to receive signals from the controller to control operation of the at least one engine; and at least one subsystem connected to the controller with the system data bus, wherein the controller is configured to at least determine an anticipatory power demand from current operating conditions of the at least one subsystem based on operational data received from the at least one subsystem over the system data bus or receive the anticipatory power demand from the at least one subsystem over the system data bus, wherein the controller is further configured to determine a total power demand that includes the nominal power demand and the anticipatory power demand and signal the total power demand to the engine control system to control the at least one engine to produce an output power that satisfies the total power demand; wherein the at least one controller initiates compensation for the anticipatory power demand prior to the at least one engine receiving the operator power request. - View Dependent Claims (11, 12, 13, 14)

15. A method comprising:
-
determining a nominal power demand of at least one engine of a machine; determining an anticipatory power demand from at least one subsystem of the machine, wherein the anticipatory power demand includes at least one of anticipatory electrical transient loads and anticipatory thermal loads from the at least one subsystem; determining a total power demand that includes the nominal power demand and the anticipatory power demand; and prior to the engine receiving an increased demand for power output, controlling the at least one engine to produce a power output that satisfies the total power demand. - View Dependent Claims (16, 17, 18, 19)
