Fault tolerant decentralized H∞ control for symmetric composite systems

Fault Tolerant Decentralized Control for Symmetric Composite Systems

This note discusses a class of large-scale systems composed of symmetrically interconnected identical subsystems. We consider the decentralized H1 control design problem and study the fault tolerance of the resulting system. By exploiting the special structure of the systems, a sufficient condition for the existence of a decentralized H1 controller is derived. Moreover, for the nominal case as ...

Decentralized H∞ Control and Reliability Analysis for Symmetric Composite Systems: Dynamic Output Feedback Case

The dynamic output feedback decentralized H∞ control and the reliability of the designed system (the maximal number of control-channel outages when the performance is still acceptable) is studied for symmetric composite systems. It is shown that the decentralized H∞ control problem can be simplified to a simultaneous H∞ control problem for two modified subsystems. A design method based on the s...

Reliable linear-quadratic control for symmetric composite systems

In recent years there has been great interest in the study of symmetric composite systems. Symmetric composite systems are systems composed of identical subsystems which are symmetrically interconnected. The motivation for studying this class of systems is due to its very diverse application areas, such as in electric power systems, industrial manipulators and computer networks (Lunze 1986, Sun...

Decentralized Adaptive Fault-Tolerant Control for Complex Systems with Actuator Faults

In this paper, an adaptive fault-tolerant control scheme is extended to large-scale interconnected systems with actuator failures and external disturbances. Based on Lyapunov stability theory, a state feedback decentralized controller is designed to compensate for the fault and the disturbance effects, using the overlapping decomposition method. Applying the inclusion principle, the interconnec...
