文摘

A saturated adaptive controller is designed for magnetic suspension systems with unknown levitated ball mass. The proposed controller can accurately estimate the unknown levitated mass. A complete Lyapunov-based stability analysis is provided. Hardware experiments verify the effectiveness of the proposed controller.
