Abstract

In this paper, an active magnetic bearing-based motor-generator(M-G) system is designed and controlled using a digital PID control concept. The plant dynamics consisting of actuator and rigid rotor dynamics are described. And some experiments are conducted with each global control and local control concept. From the whirl test, the M-G set can be controlled within about ${\pm}10{\mu}m$ gap variation at the rotational speed of 6000rpm.
