Reconfiguration-based fault tolerant control algorithm for LPV descriptor systems
Résumé
This paper presents a fault tolerant control algorithm for linear parameter varying descriptor systems using a reconfiguration-based technique. The proposed reconfiguration block comprises a virtual actuator and a virtual sensor. The virtual actuator and virtual sensor gains are calculated by solving a linear matrix inequality (LMI) problem with respect to the inputto-state stability (ISS) criterion. The main advantage of the proposed method is that it is able to achieve fault tolerance without modifying the original nominal controller. The effectiveness of the proposed approach is illustrated via a numerical example.
