Abstract: A mining machine having a control system for operating the mining machine. The control system includes a vibration monitor. The mining machine further includes a sensor and a vibration control system. The sensor senses vibration of a component of the mining machine. The vibration control system determines when the mining machine is moving in a proper cycle, triggers acquisition of vibration sensor data from the sensor in response to determining that the mining machine is moving in the proper cycle, and outputs the vibration sensor data.

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.
