电磁永磁混合悬浮系统的滑模控制器设计

电磁和永磁组成的混合悬浮系统，悬浮能耗小，能够减少悬浮系统能量的损耗。
本文建立了混合悬浮系统的数学模型，并采用了滑模控制器设计了混合悬浮控制系统，利用李亚普诺夫稳定性与极点配置结合的方法设计了系统的切换超平面和控制量，运用
SIMULINK 软件建立仿真模型并进行相关仿真实验，最后结合实际装置进行悬浮实验。

Abstract: A hybrid-levitation system with permanent magnets and electromagnets consumes
little power, and can decrease the power loss of the suspension system. In this paper the
mathematical model of this hybrid-levitation system is induced, and the method of sliding mode control is researched. A sliding mode control system is designed based on the design of flat surface of switchover, which is designed with the theory of the combination of Liapunov stability and pole assignment with SIMULINK. At last, make the research with the real device.
