1. A system for efficient machine control, comprising:
a plurality of feedback devices for identifying operating conditions of a work machine;
a controller in communication with the plurality of feedback devices and in controlling communication with a primary system and an auxiliary system, the controller comprising a processor and a computer readable storage medium having computer implemented instructions stored thereon for controlling the operation of the primary system, controlling operation of the auxiliary system, and performing a method of efficient machine operation, the method comprising:
calculating a total energy loss by:
calculating primary system energy loss based on power requests from the primary system;
calculating auxiliary system energy loss based on support requests from the auxiliary system; and
adding the primary system energy loss and the auxiliary system energy loss to arrive at the total energy loss;
adjusting a setting of the auxiliary system independent of the primary system;
repeating the calculating of the total energy loss and comparing the result to a previously calculated total energy loss until further adjustment of the setting fails to reduce the total energy loss; and
sending control requests to the auxiliary system based on the setting used when the total energy loss failed to reduce.
