N2 - Because the gyroscopic coupling effect and the imbalance force typically generate undesirable vibrations in the rotor system of magnetic suspended wind turbines when they rotate under high speed situation, a novel cross feedback based control method is proposed. Firstly, the dynamic model of a radial four-degree-of-freedom active magnetic bearing rotor system is derived. Next, a double stage cross feedback controller is designed for suppressing the vibration caused by the gyroscopic coupling effect. Moreover, an integrator and a second order low pass filter are used to improve rotor positioning performance with disturbance. Finally, better steady accuracy and disturbance rejection performance are obtained by the proposed method through comparing with a LQR controller and a traditional cross feedback controller numerically.
