  • Patent number: 9206587
    Abstract: Systems and methods for compensating dipper swing control. One method includes, with at least one processor, determining a direction of compensation opposite a current swing direction of the dipper and applying the maximum available swing torque in the direction of compensation when an acceleration of the dipper is greater than a predetermined acceleration value. The method can also include determining a current state of the shovel and performing the above steps when the current state of the shovel is a swing-to-truck state or a return-to-tuck state. When the current state of the shovel is a dig-state, the method can include limiting the maximum available swing torque and allowing, with the at least one processor, swing torque to ramp up to the maximum available swing torque over a predetermined period of time when dipper is retracted to a predetermined crowd position.

  • Publication number: 20150225921
    Abstract: Systems, methods, devices, and computer readable media for controlling the operation of an industrial machine including one or more components. A method of controlling the industrial machine includes determining a position of at least one of the one or more components of the industrial machine during a digging operation, determining a hoist bail pull setting based on the position of the at least one of the one or more components and a relationship between component position and hoist bail pull, and setting a level of hoist bail pull to the hoist bail pull setting. The level of hoist bail pull early in the digging operation is greater than the level of hoist bail pull later in the digging operation.

  • Patent number: 9103097
    Abstract: Systems, methods, devices, and computer readable media for controlling a digging operation of an industrial machine. A method includes determining a hoist bail pull associated with the industrial machine, determining a crowd torque limit value for a crowd drive based on the determined hoist bail pull of the industrial machine, and setting a crowd torque limit of the crowd drive to the crowd torque limit value to limit a torque associated with a crowd motor to the crowd torque limit value.

  • Patent number: 9074354
    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.

  • Patent number: 8958957
    Abstract: A method of controlling a digging operation of an industrial machine. The industrial machine includes a dipper connected to a dipper handle, a hoist rope attached to the dipper, and a hoist motor moving the hoist rope and the dipper. The method includes determining that the dipper is ready to be unloaded, activating a secondary tipping control operation by controlling a speed of the hoist motor, controlling an acceleration ramp rate of the hoist motor, and controlling a deceleration ramp rate of the hoist motor. The method further includes determining when the dipper is unloaded and deactivating the secondary tipping control operation.

  • Patent number: 8935061
    Abstract: Controlling a digging operation of an industrial machine that includes a dipper, a crowd motor drive, and a controller. The crowd motor drive is configured to provide one or more control signals to a crowd motor, and the crowd motor is operable to provide a force to the dipper to move the dipper toward or away from a bank. The controller is connected to the crowd motor drive and is configured to monitor a characteristic of the industrial machine, identify an impact event associated with the dipper based on the monitored characteristic of the industrial machine, and set a crowd motoring torque limit for the crowd motor drive when the impact event is identified.
