Control system for a rotating machine
First Claim
1. A system for setting a dump height of a material engaging work implement above a dump body comprising:
- a rotatable implement system at a work site having a linkage assembly including the work implement;
an implement system pose sensor for generating implement system pose signals indicative of a pose of the implement system including a pose of the work implement;
the dump body having a lower surface, the lower surface defining an initial bed height onto which material is dumped from the work implement;
a bed height sensor for generating bed height signals indicative of a bed height of the dump body; and
a controller configured to;
store a relative dump height;
determine the initial bed height based upon the bed height signals while the dump body is empty;
determine an initial dump height at which the work implement is to be positioned over the dump body based upon the initial bed height and the relative dump height;
generate a command based upon the pose of the work implement to position the work implement at the initial dump height over the dump body and dump material into the dump body;
determine a subsequent dump height, the subsequent dump height being higher than the initial dump height;
generate a command based upon the pose of the work implement to position the work implement at the subsequent dump height over the dump body and dump material into the dump body;
determine a further subsequent dump height with the further subsequent dump height being higher than the subsequent dump height; and
generate a command based upon the pose of the work implement to position the work implement at the further subsequent dump height over the dump body and dump material into the dump body.

Abstract
A system for setting a dump height of a material engaging work implement above a dump body includes a rotatable implement system, an implement system pose sensor, and a bed height sensor. A controller determines an initial bed height, determines an initial dump height, generates a command based upon the pose of the work implement, and determines a subsequent dump height higher than the initial dump height. The controller is further configured to position the work implement at the subsequent dump height, determine a further subsequent dump height higher than the subsequent dump height, and position the work implement at the further subsequent dump height over the dump body.
