Abstract Active Magnetic Bearings (AMB) have many advantages such as no friction loss, no abrasion, lubricationfree quality, and used for high rotational speed applications. A complete AMB system consists of an actuator, power amplifier, a rotor position sensor and a control system. In this paper, a closed loop decentralized Fuzzy Logic controller for Active magnetic Bearings is designed. For the numerical evaluation of control algorithm a MIMO (multiple input multiple output) mathematical model of the controlled plant is determined. The majority of industrial applications of active magnetic bearings were still based on conventional PID control system. The proposed control design is based on rule based procedure. It has been shown, that the presented FL control guarantees satisfactory high damping, low parameter variations and measurement noise of the overall system. The designed FL controller is able to maintain the rotor in center position in the final steady state. Simulations are provided to illustrate the performance of the controller.
