In this paper, a new fault isolation method is proposed. This method is based on the inverse sensitivity analysis. The idea is to identify input command and parameter perturbations using the information provided by the output trajectory deviation and the sensitivity matrices. The estimated perturbation is then used for fault isolation and possibly system reconfiguration. The proposed fault isolation method has been applied to a simulated aircraft control system and the results confirm the effectiveness of this sensitivity analysis approach.
