A　method　of　extracting　fuzzy　control　rules　from　sample　data　is　proposed　in　this　paper,　which　is　based　on　the　FCM　algorithm.　The　sample　data　is　gathered　in　the　process　of　structural　vibration　control.　Firstly,　the　input　and　output　spaces　of　the　given　sample　data　are　divided　into　several　suitable　fuzzy　regions　using　FCM　algorithm.　Secondly,　in　order　to　extract　the　fuzzy　control　rules　automatically,　a　special　network　is　designed　based　on　the　fuzzy　region　divisions.　Finally,　the　extracted　rules　are　applied　to　the　structural　vibration　control　and　the　validity　of　the　rules　is　verified.
