First Claim
1. A system for controlling power in a machine, the system comprising:
- a controller configured to;
receive request signals indicative of requested operation of at least one of an electric device and a hydraulic device;
receive operation signals from the at least one device, the operation signals being indicative of a status of the at least one device;
determine a level of power to be provided or consumed by the at least one device based on the request signals, the 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,wherein the control strategy include a subsystem control and a supervisory control,wherein the subsystem control includes at least one of an electric subsystem control for controlling operation of an electric device and a hydraulic subsystem control for controlling operation of a hydraulic device,wherein the subsystem control is configured to provide range signals for at least one of an electric device and a hydraulic device, the range signals being indicative of at least one of a range of acceptable electric power levels and a range of acceptable hydraulic power levels associated with operation of the at least one device, andwherein the supervisory control is configured to determine the control signals for controlling operation of the at least one device based on the operation signals, the range signals, and the request signals indicative of requested operation of the at least one device.

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.
