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.
