摘要
This paper studies the integrated design of fuzzy observer-based fault detection (FD) for nonlinear systems in the presence of external disturbances. To this end, we first approximate the nonlinear systems by a set of Takagi-Sugeno (T-S) fuzzy models. Then, the observer-based FD systems are studied with the aid of L-2 stability theory. In the end, a numerical example is given to show the efficiency of the proposed method. (C) 2015 Elsevier B.V. All rights reserved.
