Virtual sensors and actuators for active control of vibration in rotational degrees of freedom
Abstract
Translational sensors and actuators can be used as virtual sensors and virtual actuators for rotational DOF. When rotational DOF are directly sensed and actuated, the controller performance is generally better than when only translational DOF are employed. However, there is no net benefit to using both virtual sensors and virtual actuators: the gains obtained by one are counteracted by the other. It appears that directly sensing rotational DOF is more important for improving controller performance than directly actuating rotational DOF. The performance of the virtual sensor is sensitive to sensor separation, but the virtual actuator is less sensitive to actuator separation. The virtual actuators performed nearly as well as real moment actuators.
