Decentralized PI/PD position control for active magnetic bearings
Electrical Engineering, 2006•Springer
This paper discusses a closed-loop decentralized control for active magnetic bearings. A
cascade connection of PI and PD position controllers is proposed. The control design is
based on a simplified linearized model for one axis using a root locus. An excellent
agreement is noticeable between simulation and experimental results. It has been shown,
that the presented PI/PD control guarantees satisfactory high damping and stiffness of the
overall system.
