Controlling a digging operation of an industrial machine
First Claim
Patent Images
1. An industrial machine comprising:
- a dipper;
a crowd motor drive configured to provide one or more control signals to a crowd motor, the crowd motor being operable to provide a force to the dipper to move the dipper toward or away from a bank; and
a controller connected to the crowd motor drive, the controller configured todetermine an impact of the dipper,determine a crowd retract factor based on the impact of the dipper,compare the crowd retract factor to a threshold crowd retract factor, andset a parameter for the crowd motor drive based on the comparison of the crowd retract factor to the threshold crowd retract factor.

Abstract
Systems, methods, devices, and computer readable media for controlling a digging operation of an industrial machine that includes a dipper and a crowd drive. A method includes determining an acceleration associated with the industrial machine, determining a crowd retract factor based on the acceleration, comparing the crowd retract factor to a threshold crowd retract factor, setting a crowd speed reference and a crowd retract torque for the crowd drive for a period of time based on the comparison of the crowd retract factor to the threshold crowd retract factor.

23. A method of controlling a digging operation of an industrial machine, the industrial machine including a dipper and a crowd motor drive, the method comprising:
-
determining an impact of the dipper; determining a crowding factor based on the impact of the dipper; comparing the crowding factor to a threshold crowding factor; and setting, using a controller, a parameter for the crowd motor drive based on the comparison of the crowding factor to the threshold crowding factor. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
