| Abstract: | Based on a dynamic model of an active magnetic bearing supported flywheel system,a control model of state-space using modern control theory was established in this paper.A full-state feedback controller was designed with the method of placement of poles according to the technology specials.The effect of the mass center＇s axial offset on the whole system＇s function and its controller design was analyzed using Matlab/Simulink software.The results of simulation showed that the performances of the flywheel system designed were met the requirements.The simulation analysis was useful for the optimization of the flywheel system design. |
