Fault tolerant controllers for sampled-data systems

A general compensator architecture for fault tolerant control (FTC) for sampled-data systems is proposed. The architecture is based on the YJBK parameterization of all stabilizing controllers, and uses the dual YJBK parameterization to quantify the performance of the fault tolerant system. The FTC architecture is based on a discrete-time nominal feedback controller and with the FTC part also in discrete-time. Further, a number of problems for the design of the controller reconfiguration part in the FTC architecture is considered. It is shown how these design problems can be transformed into standard design problems for feedback controllers.
