Abstract –In this paper the design of type-2 fuzzy logic based PD controller for an active magnetic bearing system (AMB) is presented. Such a system is known to be inherently unstable. The logic techniques of the proposed method continuously observes the error signal and it's change in order to modify the parameters of a PD controller. An improved tracking performance has been achieved. Robustness against disturbance effects with various rotation speeds has also been noticed. Comparison with a regular fuzzy like PD controller shows a noticeable improvement in the tracking performance of the system, especially in the presence of disturbances. In order to ensure the stability of the system, a pole placement controller is designed first before applying the type-2 fuzzy logic PD controller.
