An Architecture for Active Fault Tolerant Control Systems

Résumé

This paper addresses the problem of active Fault Tolerant Control (FTC) for multivariable systems. The proposed scheme is composed of a nominal performance controller and a fault tolerant controller. When a fault is detected by any FDI (Fault Detection Isolation) unit, the controller structure is reconfigured by adding a FTC loop to compensate the fault. This loop is not activated in fault-free situation. Moreover, in order to decrease undesired bumps caused by the activation of FTC loop, the problem of bumpless transfer is posed within linear quadratic context. A key feature of the proposed approach is that it provides a framework for designing the FTC loop independently of the already in place controller. Simulation results demonstrate the potential of the proposed techniques
