N2 - Centrifugal compressors are susceptible to surge, a destructive state that threatens their reliable operation and shortens the service life cycle. Surge disturbance force seriously affects the stable operation of active magnetic bearing (AMB) rotor systems in magnetically suspended centrifugal compressors. This paper investigates an anti-disturbance scheme based on the disturbance-observer-based control (DOBC) to eliminate the influence of the surge force on the system stability. A disturbance observer is constructed for the harmonic surge disturbance based on the dynamics model of the AMB rotor system and disturbance subsystem. After the harmonic disturbance is observed and compensated, the convergence of the disturbance estimation error is analyzed. Simulation results of an AMB system prove that the designed method can effectively suppress the rotor displacement vibration and improve the disturbance suppression capability of the AMB system. The comparison result with the linear extended state observer verify the superiority of this method for harmonic disturbance.
