Abstract:
1. A method of controlling a digging operation of an industrial machine, the industrial machine including a dipper, a crowd motor, and a hoist motor, the method comprising: determining a torque associated with the crowd motor and a torque associated with the hoist motor; 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 including a dig force angle and a dig force magnitude; 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 being controlled by controlling at least one of the torque associated with the crowd motor and the torque associated with the hoist motor.
