摘　　要：随着现代先进制造业的发展,磁悬浮轴承作为一种新型支撑部件,受到了各行各业的广泛关注。而在整个磁悬浮轴承系统中控制环节是关键,其性能的好坏主要取决于控制器的设计与控制算法的选取。首先对磁悬浮轴承作了介绍,以控制方法为切入点,分别阐述了模糊PID控制、滑模变结构控制、鲁棒控制和最优控制的基本原理、应用和局限性。通过分析研究表明这四种控制策略能明显改善磁悬浮轴承的控制性能效果。最后对磁悬浮轴承控制作了简单总结和展望。As a new type of supporting part, magnetic bearing has been paid extensive attention around the world with the development of modern manufacturing industry. And the control link plays an important role in the whole bearing system. While the performance of control link mainly depends on the design of controller and its controller algorithm It introduces the magnetic bearing firs. Then it describes fuzzy PID control, sliding mode variable structure control, robust control and optimal control theory, applications and limitations of them. Through analysis,it can conclude that these four control strategies can improve the control performanee of magnetic bearing. At last,it makes a simple summary of the control methods in magnetic bearing,and then an outlook about it.
