摘要

A direct discrete-time design methodology for the sampled-data fault detection and isolation (FDI) problem is proposed for a nonlinear system in Takagi-Sugeno form. The generalized observer scheme is adopted, accompanied by a bank of the sensors' number of observers. A sufficient condition to find observer and residual gains, based on an accessible approximate-rather than unavailable exact-discrete-time model is proposed in terms of matrix inequalities so that it exhibits H-/H-infinity performance and asymptotic stability. An algorithm involving a convex optimization is presented using the cone complementary linearization technique. We show that the FDI observer ensures (modified) H-/H-infinity performance and Lagrange stability, when it is connected to the actual nonlinear system. (C) 2015 Elsevier B. V. All rights reserved.
