This paper presents a probabilistic approach to fault detection (FD) for nonlinear systems subject to l 2 [0, N]-norm bounded unknown input. The major contribution is to design an evaluation function for robust FD in a unified framework of l 2 -norm estimation of unknown input and determine a thresh...
