Research Interest
Research of the position sensing feedback loop in AMB applications to achieve novel and lower cost methods for sensing the rotor position with and without using dedicated position sensors, through real time identification and intelligent signal processing of the measurement data.

Active magnetic bearing is a complicated mechatronic system where rotor is levitated with electromagnets. Contactless rotor operation enables high rotational speeds. This is useful in many high-speed applications where traditional bearings cannot be used due the lack of the mechanical strength. Because magnetic bearings are naturally unstable system, electromagnets need to be controlled actively.

Several position measurement sensors are needed to determine the rotor position. Knowledge of the rotor position is fed to the controller where control signal is calculated for the electromagnets to keep the rotor in the reference position. Controller requires several inputs and outputs to control this kind of system. The commercial position sensors used in the position feedback loop are expensive and increase the cost of the whole AMB-system, decreasing the adoption of the technology in the industry.
