Damping mechanisms based on gyroscopic moments are studied, and their characteristics are compared with other conventional damping mechanisms. The generalized gyroscopic stabilizing mechanism of Schlik's gyroscope is analyzed, and the optimal design method is derived. The resulting stabilizing effect is compared with the rotational dynamic damper. It turns out that the effect of the gyroscopic stabilizer depends on the rotating speed of the gyroscope; thus there is no essential limitation by the inertial moment such as there is with the dynamic damper. The gyroscopic moments can be used more actively for the improvement of transient responses. The single-gimbal CMG (control moment gyro) is compared with the RW (reaction wheel), and the driving torque for the actuators is discussed. Experiments with a single-gimbal CMG for a pendulum are carried out and the results prove the efficiency.
