Fault tolerant control of large-scale systems subject to actuator fault using a cooperative approach

Abstract

In this article, a new approach to tackle the problem of fault tolerant control of large-scale systems is proposed. The main goal of this so-called cooperative fault tolerant control approach is to overcome the undesired effects of an actuator fault propagated through the whole large-scale system. This is done using a cooperation of a subset of subsystems. The approach is first clarified through an illustrative example and is then completely formulated. It is then solved in a special case called “cooperative reconfiguration” using the previously defined virtual actuator technique. Finally, results of this article are implemented on the load–frequency control problem of a power system.
