This study presents and experimentally demonstrates two vibration control structures for mitigation of gear mesh vibration using the drive motor, which also serves as the prime mover. Using the drive motor for vibration mitigation eliminates the need for a dedicated actuator. However, the dual-role of the drive motor in speed-controlled systems can result in a conflict — where the speed controller counteracts the vibration controller. The two vibration control structures, designed for speed and torque control of systems, are based on an adaptive learning rate Filtered-x Least Mean Square algorithm and can be implemented as add-ons, without the need to reparametrise the motor controller.
