Abstract
This article presents a model of rigid rotor supported by active magnetic bearings (AMB). Mathematical formulation of magnetic forces generated by AMB has been developed. Equations of motion of rigid rotor supported by controllable AMB with and without control law are presented. Eigen structure assignment method is used to change the eigenfrequency of mechatronical system. Numerical simulations are compared with experimental measured data. The simulations presented in this paper correspond with measurement.
