Abstract

Active magnetic bearings (AMBs) are widely applied in modern high-speed
drives. The properties of the electrical ciruit related to AMB dynamics
should be known when designing the control, but also the monitoring
during the operation of the drive is important. This paper addresses
issues in the online estimation of dynamic resistance and inductance in
AMB application. The approach considered in this paper is based on
current oversampling and slope estimation. The approach is validated
with a MOSFET based H-bridge that is connected to RL-load. The results
show that the used approach provides reasonable estimation results.
