Résumé

Based on the techniques of high gain observer and adaptive estimation,an algorithm is proposed in this paper for sensor fault estimationin nonlinear systems. It is essentially assumed that a high gainobserver exists for the fault-free system. A high gainadaptive observer is then designed for sensor fault estimation.The convergence of the algorithm is established under a persistentexcitation condition.
