Abstract:
Th is paper uses a guaranteed cost contro lmethod to design a contro ller o f the grinder spindle system supported by e lectromagnet ic bearing s ( EMB s) . In view o f the system non linearity, a digita l var-i able ga in contro ller is designed to so lve the contrad iction betw een large globalmo tion and h igh st iffness. The results from the simulation and test show that the robust performance and the robust stab ility o fEMBs are guaranteed by the guaranteed cost contro lmethod, and the contradict ion betw een large g lobalmotion and h igh st iffness is solved effectively by the designed d ig ital variable gain contro ller。
