摘要：

This work investigates the problem of designing a fault detection filter for discrete-time nonlinear systems using H-/H-infinity-optimization that simultaneously improves robustness against disturbances and enhances sensitivity to faults. Sufficient conditions for the solvability of this problem are provided in the form of a pair of coupled Hamilton-Jacobi inequalities. Both the finite-horizon and the infinite-horizon problems are addressed. The proposed methodology is elaborated through a couple of examples. (C) 2014 Elsevier B.V. All rights reserved.
