| Abstract: | 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. |
