摘　　要：该文采用保成本控制方法设计电磁轴承磨床电主轴系统控制器。考虑系统非线性,设计了数字变增益环节以调节系统大范围运动与高刚度的矛盾。通过仿真分析和实验测试表明保成本控制方法保证了电磁轴承磨床电主轴系统鲁棒稳定性和鲁棒性能,同时也表明设计的数字变增益环节有效地解决了系统中存在的大范围运动与高刚度的矛盾。This paper uses a guaranteed cost control method to design a controller of the grinder spindle system supported by electromagnetic bearings (EMBs). In view of the system nonlinearity, a digital variable gain controller is designed to solve the contradiction between large global motion and high stiffness. The results from the simulation and test show that the robust performance and the robust stability of EMBs are guaranteed by the guaranteed cost control method, and the contradiction between large global motion and high stiffness is solved effectively by the designed digital variable gain controller.
