Abstract :
This paper provides a method for designing a sliding mode controller with outer-loop integration for magnetic bearings with experimental evaluation. The experimental apparatus was modeled using parameter estimation. Experimental testing verified the tuning goal and showed that the sliding mode controllers performed better in disturbance rejection than the PD controller and are comparable to an optimal nominal controller. The work highlights conditions for controller selection
