This article presents a fuzzy logic-base control scheme for a non-linear magnetic bearing system that is subject to time delay in a feedback loop. A new Takagi—Sugeno fuzzy model is proposed to represent the non-linear magnetic bearing. Based on the new fuzzy model, an output feedback controller is designed in terms of a proposed delay-dependent stability criterion which guarantees the asymptotic stability of the fuzzy model. The results of simulation verified the effectiveness and superiority of the proposed method.
