Abstract
In this work, we focus on monitoring and reconfiguration of an Adaptive Model Reference (MRA) Fault-Tolerant Control (FTC) for large-scale system. This particular class presents an interconnected and networked control system (INCS). Moreover, the system can be decomposed into N-interconnected subsystems communicating with network. Then the global output of INCS and one or more outputs of N-interconnected and networked control subsystems are attacked by sensor faults. Therefore, an active Fault-Tolerant (FT) approach, say the model reference adaptive control of linear systems, is used in order to guarantee not only the stability of an overall INCS globally, but also all local stabilities of N-networked control subsystems with strong interactions, delay and additive faults. Moreover, two architectures: centralized and decentralized adaptive controllers are designed to compensate the sensor faults for different internal structures of systems which are subject of this paper. The law adaptations which make the different faulty systems stable are given. A simulation example of an overall INCS consisting of three interconnected and networked control subsystems and involving stabilization of unstable steady-states is used to demonstrate the efficiency of the proposed approach.
