Since active magnetic bearings have been employed in turbo-machinery, a corresponding simulation technique combined with rotor dynamics and a controller network is required for design, controller tuning, and so on. This paper presents the principle of the simulation method and its applications to stability estimation, unbalance responses and frequency response of a servo control system. The rotor system is reduced to a small model by the quasi-modal modeling that we have developed. The control network is expressed by the usual state equations. Both the models are then combined in a global system equation for the simulation analysis. In addition to the usual control law, e. g. , PID, the observer based state feedback and so on, the developed program is capable of covering the tracking filter with rotational speed and cross talk between X and Y channel control, which are related to empirical knowledge of the rotor vibration control. Some examples of the numerical simulation are presented for demonstrating practical applications of the developed program.
