Comparaison of the data reconciliation and finite memory observer at the inverted pendulum
Résumé
In this paper, we propose two methods to detect and localize instrument or actuator failures in linear dynamic systems. These methods are based on analytical redundancy and use a simultaneous states and inputs estimation. Using the concept of standardized least square residuals, residuals can be generated in a umber of ways and the design of fault detection and fault isolation scheme can be presented. The performances of the proposed methods are illustrated on a real process: an inverted pendulum.
