Abstract

In this paper an Active Magnetic Bearing (AMB) spindle is considered as a rigid rotor mounted on two bearings with stiffness and damping characteristics. The equations for small perturbations of the rotor are derived in the form of a multi-input, multi-output transfer function matrix description, enabling the multivariable frequency response matrix for the system to be computed. Thereafter a control system configuration comprising four vibration sensors and two actuators is proposed. Using the multivariable frequency response matrix of the system, a model based feedback controller is derived. A numerical example is used to illustrate that the effects of disturbances can be rapidly diminished reducing the net radial displacement of the spindle to zero. The advantages of this scheme for control of AMB spindle is discussed.
