Abstract: Method of controlling multiple variable displacement hydraulic pumps determined relative to operator commands. If non-second-pump-dominated command, a respective adjusted displacement request is determined based upon the lesser of the operator requested torque limited displacement and an adjusted torque limited displacement that calculated based upon and the torque limited displacement of the respective pump and a scaling factor calculated based upon the first relief valve set pressure and respective pump pressure. If second-pump-dominated command, the set pressure of a relief valve associated with one of the pumps is instead utilized in calculating the scaling factor in the above strategy.

Abstract: A power system for a machine is provided. The power system includes an operator interface for entering an operator command relating to one or more functions of the machine. The power system includes a hydraulic pump and an engine configured to provide power to the hydraulic device. A controller is in communication with the operator interface, the hydraulic device and the engine. The controller is configured to consider operator skill level information relating to a skill level of the operator of the machine and to determine at least one desired power system operating parameter based on the operator command and the operator skill level information and to adjust at least one of the hydraulic pump and the engine based on the desired power system operating parameter.
