1. A method of compensating swing control of a dipper of a shovel, the shovel including a swing motor, the method comprising:

  • determining, by at least one processor, a current swing direction of the dipper;

    determining, by the at least one processor, a direction of compensation opposite the current swing direction of the dipper;

    monitoring, by the at least one processor, an acceleration of the dipper;

    detecting, by the at least one processor, an impact of the dipper with an object when the monitored acceleration is within a determined range of acceleration values;

    modifying, by the at least one processor, a swing torque value for the swing motor; and

    applying, by the at least one processor, the modified swing torque value for the swing motor to slow a current swing speed of the dipper in response to detecting the impact of the dipper with the object.
