Fault tolerant control - a residual based set-up

A new set-up for fault tolerant control (FTC) for stable systems is presented in this paper. The new set-up is based on a simple implementation of the Youla-Jabr-Bongiorno-Kucera (YJBK) parameterization. This implementation of the YJBK parameterization will allow a direct and simple re-configuration of the feedback controller. Another central part of fault tolerant control is fault diagnosis. The controller implementation can be applied directly in connection with both passive diagnosis (PFD) as well as with active fault diagnosis (AFD). The presented FTC set-up is investigated with respect to sensor reconfiguration. Actuator reconfiguration can be dealt with in a similar way.
