This paper presents the cooperative control between the active magnetic bearing
system and the permanent magnet synchronous drive. More specifically, the coupling between
the vibration control and sensorless drive control is considered since both systems have the
ability to estimate the angular speed. The coupling of the estimated speed in each controller
is considered. Also, a modified start-up procedure for the sensorless vector control had to be
developed when the drive is combined with the AMB system to accommodate the low friction
which does not yield damping of the speed perturbation at start-up. Simulation results are
presented for the developed control using detailed models for both systems
