Summary
This paper deals with the problem of an unbalance vibration in magnetic bearings. An efficient damping control scheme for the vibration is proposed. First, the state equation of a magnetic bearing system in which unbalance of a rotor is taken into consideration is shown. Next, the control system achieving the rotation around the geometrical axis is proposed. Here we formulate the control problem within a framework of the so-called Robust Servomechanism problem, and we design the control law using the Selective Turn-over method. Finally, the effectiveness of the control system is actually confirmed by several experimental results.
