Abstract
A payload control system includes a sensor system and a force sensor system. A controller determines a calibration machine state, a calibration linkage force, and machine calibration parameters based at least in part upon the calibration machine state and the calibration linkage force. The controller also determines a loaded implement machine state, a loaded implement linkage force, and a mass of the payload based at least in part upon the machine calibration parameters, the loaded implement machine state, and the loaded implement linkage force.
