Robust fuzzy control of a magnetic bearing system subject to harmonic disturbances Academic Article

abstract

• This paper proposes a robust fuzzy logic-based control scheme for a rotating active magnetic bearing (AMB) system. We represent the nonlinear magnetic bearing by means of a Takagi-Sugeno-Kang (TSK) fuzzy model. Subsequently a systematic synthesis procedure is used to derive a nonlinear fuzzy logic control strategy that overcomes the inherent characteristics of displacement sensitivity and position-dependent nonlinearity of AMB. Experimentation and simulation results demonstrate that the proposed fuzzy controller yields robustness against harmonic disturbances and parameter uncertainties.
