Fault Estimation and Fault Tolerant Control for Discrete-Time Dynamic Systems

Fault-Tolerant Dynamic Systems

Modular redundancy (system replication) and other traditional techniques for fault tolerance in dynamic systems are expensive, and rely heavily — particularly in the case of systems operating over extended time horizons — on the assumption that the error-correcting mechanism (e.g., voting) is fault-free. Herein, we construct redundant dynamic systems in a way that achieves tolerance to transien...

Fault Tolerant Control in Dynamic Systems

Abstract: In this paper a method for fault tolerant control in dynamic systems is presented. In an integrated design, the proposed approach is composed of two stages. The first step is the detection and isolation of the failed component while the second step is represented by the reconfiguration mechanism. It consists in the estimation of new control parameters after evaluation of the performan...

Fault Tolerant Real Time Systems

Real time systems are systems in which there is a commitment for timely response by the computer to external stimuli. Real time applications have to function correctly even in presence of faults. Fault tolerance can be achieved by either hardware or software or time redundancy. Safety-critical applications have strict time and cost constraints, which means that not only faults have to be tolera...

Fault-Tolerant Control for LPV systems based on Fault Compensator

This paper proposes a fault-tolerant control (FTC) scheme for polytopic linear parameter varying (LPV) systems. We first propose a fault compensator whose structure is simple, but effective against actuator faults. Then, in order to show its basic idea, we consider a state feedback FTC scheme based on the fault compensator. Next, the FTC algorithm is extended to output feedback FTC scheme. The ...
