Extension of model-reference based estimator for fault isolation in a bioprocess

The paper deals with fault-isolation time problem of the adaptive observers based scheme. The Fault Detection and Isolation (FDI) method is applied to an alcoholic fermentation process using an Estimator based on the approach of the Model Reference (EMR). We propose in this work a new structure of the estimator gains in order to improve the convergence speed of the EMR observer and by the way the time needed to isolate the fault.
