ABSTRACT Adaptive Neuro-Fuzzy Inference System (ANFIS) is used to design fuzzy reduced order observer for solving the problem of unbalance in magnetic bearing systems. Nonlinear model of magnetic bearing with unbalance is very complicated and coupling between various states cannot be neglected. With classical methods no one can eliminate disturbances without linearization of the system and neglecting some terms from the nonlinear model. In this paper ANFIS is used to acquire desired membership functions of the fuzzy rules for reduced order observer to achieve rejection of unbalance. Simulation results show that fuzzy observer can eliminate the effect of unbalance at any rotational speed.
