Advanced control for active magnetic bearing (robust control for flexible rotor magnetic bearing considering spillover and gyroscopic effects)

摘要

In this paper, methods of designing a robust controller are proposed to solve spillover and gyro problems. A control system is designed based on a H{sub}∞Loop Shaping Design Procedure. By shaping open loop properly, the designer can stabilize high order model while giving low order modes to enough damping. A Hadamard weight is added to attenuate coupling caused by gyroscopic effects. The effectiveness of the proposed method is confirmed by experiments.
