Title: Application of hedge algebra-based fuzzy controller to active control of a structure against earthquake.
Authors: Anh, N. D.; Bui, Hai‐Le; Vu, Nhu‐Lan; Tran, Duc‐Trung
Abstract: SUMMARY Active control problems of seismic-excited civil structures have attracted considerable attention in recent years. In this study, a design procedure of the hedge algebra-based fuzzy controller (HAFC) is investigated for a class of high-rise building systems with active tendons, which are subjected to seismic activity. In the HAFC, semantics of linguistic terms is obtained through semantically quantifying mappings (SQMs) without using any fuzzy set. Hence, the design of a HAFC leads to determining parameters of SQMs, which are fuzziness measures of primary terms and linguistic hedges occurring in a fuzzy model. To prove the validity of the HAFC in the aforementioned problem, an earthquake-excited 10-floor building with two actuators is numerically simulated. Copyright © 2011 John Wiley & Sons, Ltd.
