Abstract
This communication deals with the problem of fault detection and localization for a wide class of nonlinear systems subjected to bounded nonlinearities. A dedicated nonlinear observer scheme (DNOS) for fault detection and identification of observable systems is proposed. I. INTRODUCTION State observation of nonlinear dynamical systems is becoming a growing topic of investigation in the specialized literature. The reconstruction of the time behaviour of state variables remains a major problem both in control theory and process diagnosis. Researchers attention is being particularly focused on the design of adaptive observers for on-line process states estimation. There is increasing awareness that ensuring robustness in performance requires simpler and stable adaptive observer schemes. Linear systems have received considerable attention [1], [2] leading to several stable adaptive observer systems [3], [4], [5], [6]. Linear observer systems involving unknown inputs have also been develop...
