Abstract: This paper explains how to use an adaptive High-Gain observer in sensor diagnosis problems. This type of observer allows to switch between a classical Extended Kalman Filter and High-Gain observer according to an innovation function. Combined with a standard technique of residual generation, this approach is very efficient to determine fault occurence in the non-linear dynamical systems. We present the obtained results on a wastewater treatment system.
