中文说明：磁悬浮技术在现代社会里应用非常广泛，在我国，该技术已经应用到磁悬浮列车，磁悬浮轴承，磁悬浮机床等。磁悬浮系统的建立，可以避免了物体之间的摩擦和磨损，能延长设备的使用寿命，改善设备的运行条件。同步控制技术在现代生产实践中，已有广泛的应用，可以获得满意的控制精度和工作稳定性。本文采用磁悬浮技术来消除龙门移动式数控机床中移动部件与静止导轨之间存在的摩擦，提出采用模糊PI状态反馈控制对单电磁铁悬浮系统设计控制器，仿真结果表明，系统准确跟随输入，没有稳态误差，并与状态反馈控制进行了对比。最后，详细论述了模糊PID控制策略设计系统的同步控制器。本文采用两套相同的磁悬浮装置，并且给定相同的输入，将两个磁悬浮系统的误差作为同步控制器的输入，通过此控制器的反馈补偿控制实现横梁同步悬浮。仿真结果表明，本文提出的控制方案有效，系统在扰动作用下动态同步误差很小，并限制在允许值范围内。
English Description：
Maglev technology in modern society is widely used in our country, the technology has been applied to the magnetic levitation train, magnetic bearings, levitation machine tools. Build maglev system, to avoid the friction and wear between objects, can extend the life of equipment, improving the operating conditions of the equipment. Synchronous control technology in modern production practice, has been widely used, can obtain satisfactory control accuracy and stability. In this paper, magnetic levitation technology to eliminate between mobile gantry CNC machine tools in moving parts and stationary rail friction proposed fuzzy PI state feedback control system design of single electromagnet suspension controller, the simulation results show that the system accurately follows the input, there is no stable state error, and with the state feedback control were compared.Finally, a detailed discussion of the synchronous controller fuzzy PID contr
