Abstract: A control system for controlling a motion of an auger tube of a combine harvester comprises a dynamic pre-filter, a position controller, and a speed controller. The dynamic pre-filter receives a desired position value for the auger tube and generates a filtered desired position signal which changes the desired position value from an old value to a new value over a time period. The position controller receives a first difference between the filtered desired position signal and an actual position of the auger tube. The position controller generates a desired angular speed signal that varies according to the first difference. The speed controller receives a second difference between the desired angular speed signal and an actual speed of the auger tube. The speed controller generates an actuator signal that varies according to the second difference and is received by an actuating system that moves the auger tube.
