A totally active magnetic bearing system is composed of four subsystems : three with one degree of freedom related to translational motion and one with two degrees of freedom related to rotational motion. One of the major problems associated with the design of magnetic bearing control systems is that the two rotational motions interact on each other by gyroscopic effects caused by. spinning of the rotor, which need not be considered in designing electromagnetic levitation systems. Therefore an instrument for experimenting on controls of the gyroscopic coupled system is developed in this paper. The mechanism of the instrument resembles the mechanism of the two-axis gyroscope; a feature of the instrument is that the motions of the gyro are controlled by attractive forces of the electromagnets. Thus the instrument has the same dynamics as the subsystem related to the rotational motions of the magnetic bearing systems. The control system of the instrument is designed by utilizing the optimal regulator theory. The effectiveness of the optimal regulator is experimentally studied.
