This paper deals with the problem of fault detection and isolation in nonlinear systems. A new design method for residual generation is developed, based on geometric approach. In this work, existence conditions given by De Persis and Isidori (C. De Persis and A. Isidori, 1999 and C. De Persis and A. Isidori, 2000) are considered. In order to illustrate the proposed results, a simulation example is carried out.
Keywords: Nonlinear system - Diagnosis - Isolation - Geometric approach
