A system for efficient machine control may include feedback devices for identifying operating conditions of a work machine and a controller for controlling a primary system and an auxiliary system. The controller may calculate a total energy loss by adding a primary system energy loss based on power requests from the primary system to an auxiliary system energy loss based on support requests from the auxiliary system. The controller may adjust a setting of the auxiliary system, repeat the calculating of the total energy loss, and compare the result to a previously calculated total energy loss until further adjustment of the setting fails to reduce the total energy loss. The controller may then send control requests to the auxiliary system based on the setting used when the total energy loss failed to reduce.

ALIGNMENT OF MACHINE TO INSTALL STEERING FRAME LOCK
A method for steering alignment calibration of an articulated machine having front and rear frames pivotally connected by an articulation joint to steer the machine may include displaying a steering alignment calibration screen with a target steering angle between the frames and a calculated steering angle. The calculated steering angle may be determined based on a sensed steering angle and a calibration steering angle. The machine is steered until the displayed calculated steering angle is equal to the target steering angle. If an actual steering angle of the machine is not equal to the target steering angle, further steering is performed until the actual steering angle is equal to the target steering angle. The calibration steering angle may be recalculated and stored for future use when the actual steering angle is equal to the target steering angle but the calculated steering angle is not equal to the target steering angle.
