Multiple Fault Detection in a Noisy System

In this paper, we are interested in monitoring a dynamic system in order to contribute to the establishment of a general procedure for detection and fault isolation.In this regard and based on the mathematical model of the process, we use an observer to generate residualsfor a decision in a stage of monitoring and diagnostic system when disruptions or defects occur.Our contribution isthe proposal of a diagnostic method when multiple faultstype actuators orsensors affect the system
