Design of a fault-tolerant control scheme for two collaborative subsystems

Abstract A fault-tolerant control method is proposed for a class of dynamic systems including two subsystems. These two subsystems work together in order to perform a joint task. The proposed fault-tolerant control aims at obtaining a control strategy that can use the healthy subsystem to compensate the faulty one. When one subsystem is subjected to faults, the other subsystem is used to accommodate faults and compensate the influences onto the total system, leading to a fault-tolerant control of the whole system. Theoretical analysis and computer simulations illustrate the validity of this method.
