Abstract

The plant dynamics of rotor/magnetic bearing systems are parameter dependent on the rotation speed due to gyroscopic effects. This paper introduces a novel robust gain-scheduled H? controller design method based on LMI techniques which allows the formulation of multiple design objectives in one unified framework. In particular, hard/soft control design is considered, and the importance of achieving performance over the whole speed range is addressed. If speed dependence is ignored in the controller design, system instability might occur. However, the LMI based approach is shown to maintain closed loop stability over the full speed range.
