Abstract
Controlling a digging operation of an industrial machine. The industrial machine includes a dipper, a crowd motor, and a hoist motor. The control includes determining a torque associated with the crowd motor and a torque associated with the hoist motor and determining a dig force vector for the dipper based on the torque associated with the crowd motor and the torque associated with the hoist motor. The dig force vector includes a dig force angle and a dig force magnitude. The method also includes determining a value for the dig force angle of the dig force vector, and controlling, using a processor, the dig force magnitude based on the determined value for the dig force angle. The dig force magnitude is controlled by controlling at least one of the torque associated with the crowd motor and the torque associated with the hoist motor.
