FDIR and Integrated Evaluation For Fault-Tolerant Elevator System
نویسندگان
چکیده
This paper presents a fault detection, isolation and reconstruction (FDIR) mechanism for the fault-tolerant system. A self-detection component is introduced to the normal dual-channel redundant system, and the component can detect the outputs of the behavior model and the nominal system model. The control strategy is reconfigured by using the differences between the outputs of the behavior model and nominal model so as to improve the reliability and performance requirements of the system. The fault-tolerant management mechanism considers the metrics of the reliability of the elevator system and the performance requirements. Based on the evaluation tool developed on Matlab/Simulink, we assess the case of the elevator fault-tolerant system with the self-detection component and verify the effectiveness of this methodology.

متن کاملAn Integrated Process for FDIR Design in Aerospace
The correct operation of complex critical systems increasingly relies on the ability to detect and recover from faults. The design of Fault Detection, Isolation and Recovery (FDIR) sub-systems is highly challenging, due to the complexity of the underlying system, the number of faults to be considered and their dynamics. Existing industrial practices for FDIR are often based on ad-hoc solutions,...

In earlier work we have proposed the concept of the dynamic group maximum matching for grouping the system graph into groups of different sizes according to the tasks arriving at the system. Also, we have developed a more efficient integrated fault-tolerant technique for ultra-reliable execution of tasks where both hardware (processors and communication channels) and software failures, and on-l...

some applications are critical and must designed Fault Tolerant System. Usually Voting Algorithm is one of the principle elements of a Fault Tolerant System. Two kinds of voting algorithm are used in most applications, they are majority voting algorithm and weighted average algorithm these algorithms have some problems. Majority confronts with the problem of threshold limits and voter of weight...
