| Abstract: | The dynamical analysis of an electric magnetic bearing rotor system is presented in this paper. The rotor is discreted into a multi mass model and logarithmic decrement has been applied as a stability index of the system. On such a base, the effect of controller parameters of the electric magnetic bearing on the logarithmic decrement and natural frequency of each system model is analyzed and discussed. The results are used to direct the design of parameters of a controller.In comparison with the single mass rotor model and pole placement method applied in most other published papers ,the analysis presented in this paper is more accurate and practical. |
