능동형 자기 베어링 시스템의 디지털 퍼지 제어

In this paper, we present a systematic procedure to design the digital fuzzy controller for an active magnetic bearing (AMB) control system. The continuous-time Takagi-Sugeno (T-S) fuzzy model is employed to represent the nonlinear magnetic bearing system. Then, based on the obtained fuzzy model, sufficient conditions are derived in terms of linear matrix inequalities (LMIs) for digitla control approach. For achieving efficient digital statbility, we concern the intelligent digitl redesign (IDR) method for AMB control system
