Abstract
Disclosed is a system for controlling power in a machine. The system includes a controller configured to determine a level of power to be provided or consumed by at least one of an electric device and a hydraulic device based on request signals, operation signals, and a control strategy for controlling at least one of electric power and hydraulic power for the machine, and provide control signals for controlling operation of the at least one device. The control strategy includes a subsystem control and a supervisory control. The subsystem control includes at least one of electric and hydraulic subsystem controls for controlling operation of at least one of an electric device and a hydraulic device. The subsystem control is configured to provide range signals indicative of at least one of a range of acceptable electric power levels and a range of acceptable hydraulic power levels, and the supervisory control is configured to determine the control signals.
