摘要：

A robust control of an active radial homopolar magnetic bearing system is considered in the paper. The robust control of a rigid rotor vibration is designed analytically and confirmed by experimental investigations. A digital signal processor (DSP) is used to implement the control algorithm and the position control loop is executed in real time. The stability of system with disturbance interaction is discussed. The success of the robust control is demonstrated through results of computer simulations. Finally, experimental results show the effectiveness of the control system as well as good initial responses/transient responses and robustness of the designed controller. (C) 2007 Elsevier Ltd.
