Fault Tolerant Decentralized Control for Symmetric Composite Systems
نویسندگان
چکیده
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 well as for contingent situations characterized by control channel failures, the poles and the H1-norm of the closed-loop system can be calculated easily based on certain systems of reduced dimensions. Consequently, the tolerance to actuator failure can be easily tested.

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...
متن کاملDecentralized 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...
متن کاملA Service-Based Decentralized Architecture for ECU Fault Tolerant Control
The purpose of this master thesis is to contribute a service-based decentralized architecture for Electronic Control Unit (ECU) with fault tolerant control. As ECU systems are becoming large-scaled, centralized-architecture fault tolerant control is facing challenges in performance, complexity and engineering, for its dependencies, nonmodular, non-scalable and so on. In Scania’s ECUs, the archi...
