摘　　要：电磁轴承是磁悬浮原理在机械领域中的一个应用实例,因其具有运动阻力小、无接触摩擦和磨损、功耗低以及寿命长等优点,而受到科学家和企业家的普遍关注,又由于其设计问题涉及多个学科领域的专业知识而增加了难度,使得其推广和应用受到一定的限制.利用机器人的理论和技术可赋予电磁轴承以专业设计人员的“智慧”,使它能够“独立”地“鉴别”将要“面对”的任何转子(或悬浮体),再根据“已有的专业知识”,包括“设计经验”,对转子(悬浮体)系统进行静动特性分析的综合分析,“在线设计”出系统合适的控制参数,实现稳定的悬浮支承.这就是智能磁力轴承的主要思想.Magnetic bearing is an application in machine building based on the principle of magnetic levitation. Its good properties such as low motion resistance, absence of contact friction and wear and tear, low power consumption, and long service life have attracted considerable attention from scientists and manufacturers. However design of the bearing system is quite difficult as it involves a wide range of knowledge, limiting its wide spread applications. By using of the robot technology, the bearing can be made to possess human intelligence to recognize the state and dynamical parameters of any rotor （or body） automatically and independently. Design of the system control parameters can be carried out online based on the intelligence and experiences. This is the idea of intelligent magnetic bearing （IMB）, and may become a kind of the bearings suitable to be used in airplanes.
