Fault tolerant control design of nonlinear systems using LMI gain synthesis

Résumé

In this paper, an active Fault Tolerant Control (FTC) strategy is developed to nonlinear systems described by multiple linear models to prevent the system deterioration by the synthesis of adapted controllers. By considering that Fault Detection, Isolation (FDI) and estimation is realized, the synthesis of an appropriate combination of predesigned gains is performed. The main contribution concerns the design of state feedback gains through LMI both in fault-free and faulty cases in order to preserve the system performances. For each separate actuator, a robust pole placement is designed by pole clustering. The effectiveness and performances of the method are illustrated in simulation by considering a nonlinear system: a Three-Tank system.
