A slewing frame configured with a piezoceramic strut is discussed. The slewing of aframe similar to a satellite solar panel induces both torsional and bending vibration in theframe. The torsional modes are relatively uncontrollable with the motor used to slew theframe. This provides a natural application of active structure technology. A frame elementis replaced with a dynamically equivalent element which contacts eight self-sensingpiezoceramic actuators. These actuators render the torsional modes controllable. Thisanalysis and experiment are then used to investigate various control laws for performingvibration suppression while slewing.
