【摘要】 以五自由度的磁悬浮平台为研究对象,介绍了其系统组成和工作原理,建立了磁悬浮平台的数学模型,该平台具有与五自由度磁悬浮轴承相似的工作原理。针对磁悬浮系统的开环不稳定和强烈非线性的特点,采用模糊控制方法实现了对磁悬浮系统的数字控制。利用Matlab模糊逻辑工具箱中的FIS(Fuzzy Inference System)编辑器,结合Simulink工具箱建立模糊控制系统的仿真模型,并对其进行了仿真研究。仿真结果表明,该控制器具有一定的干扰抑制能力和鲁棒性。更多还原

【Abstract】 Five degree freedom magnetic floating table is studied,which has the same working principle as the five degree freedom magnetic floating bearing.The stracture and working principle of the magnetic floating table are introduced,and its mathematical model is established.The problems of opening loop instability and very strong nonlinearity of magnetic floating systems are solved by using fuzzy control technology,which realized the digital control of magnetic floating systems.Simulation results are obtained by using Fuzzy Inference System editor of fuzzy logic toolbox in software Matlab.Simulation results demonstrate both disturbance control ability and performance robustness of the developed controller.更多还原
