Abstract
In this paper, we show a Gain Scheduling(GS) controller design method for Active Magnetic Bearing System(AMB). Gyroscopic effect corresponding to the rotational speed of the shaft occurs in a magnetic bearing system. Therefore, the shaft of AMB becomes unstable. The time-varying parameter is rotational speed. The varying parameter can be measured on line. By designing the GS controller,it has a scheduling parameter of a rotational speed of the shaft, we try to guarantee stability and improve the control performance. The problem can be formulated as solving finite set of linear matrix inequalities. The effectiveness of the proposed method is verified by simulation.
