Abstract

In order to pass through the bending critical speed of flexible rotor system supported by magnetic bearing, the phase changes from the rotor's flexible deformation to magnetic force at bending critical frequency should be adjusted to increase its damping. In this paper, the optimal control phase of AMB controller is deduced from the theoretical model firstly. Then, the actual control phase is obtained using the method of dynamic analysis combined with model reference identification. Optimal phase to be compensated is determined finally. The experimental result shows that AMB controller added with a optimal phase compensator makes the rotor's flexible deformation minimum nearby the bending frequency.
