Abstract
A system for controlling power in a machine includes a controller. The controller is configured to receive request signals indicative of requested operation of at least one of an electric device and a hydraulic device. The controller is further configured to determine a requested level of power required to meet the requested operation and determine an ability of the engine to supply the requested level of power. The controller is further configured to provide control signals to the at least one device to either supply power to the engine or receive power from the engine based on the ability of the engine to supply the requested level of power. The controller is also configured to provide control signals to the engine to control speed and output of the engine, wherein the control signals provided to the engine and the at least one device result in operation of the engine within a speed range of a target engine speed.
