System and method for managing machine power system
First Claim
1. A power system for a machine, the power system comprising:
- an operator interface for entering an operator command relating to one or more functions of the machine;
a hydraulic pump;
an engine configured to provide power to the hydraulic pump; and
a controller in communication with the operator interface, the hydraulic pump and the engine,the controller being configured to;
consider operator skill level information relating to a skill level of the operator of the machine,determine at least one desired power system operating parameter based on the operator command and the operator skill level information,apply a rate of change limit on the determination of the at least one desired power system operating parameter, andadjust at least one of the hydraulic pump or the engine based on the at least one desired power system operating parameter.

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.

18. A machine comprising:
-
an operator interface for entering operator commands relating to one or more functions of the machine; a work implement; a hydraulic device for driving movement of the work implement; an engine configured to provide power to the hydraulic device; and a controller in communication with the operator interface, the hydraulic device and the engine, the controller being configured to; consider operator skill level information relating to a skill level of an operator of the machine, consider machine utilization information relating to utilization of the machine, determine at least one desired power system operating parameter based on the operator commands, the operator skill level information and the machine utilization information, apply a rate of change limit on the determination of the at least one desired power system operating parameter, and adjust at least one of the hydraulic device or the engine based on the at least one desired power system operating parameter.
