A fault tolerant control scheme for collaborative two sub-systems

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 sub-system 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 have illustrated the validity of this method
