Abstract

This paper presents a novel technique for improved voting by adaptively varying the membership boundaries of a fuzzy voter to achieve realistic consensus among inputs of redundant modules of a fault tolerant system. We demonstrate that suggested dynamic membership partitioning minimizes the number of occurrences of incorrect outputs of a voter as compared to the fixed membership partitioning voter implementations. Simulation results for the proposed voter for Triple Modular Redundancy (TMR) fault tolerant system indicate that our algorithm shows better safety and availability performance as compared to the existing one. However, our voter design is general and thus it can be potentially useful for improving safety and availability of critical fault tolerant systems.
一种改进容错系统投票的模糊隶属度划分方法
本文提出了一种改进投票的新技术,通过自适应改变模糊投票者的隶属边界,使容错系统冗余模块输入之间达到现实一致。我们证明,与固定成员分区投票人实现相比,建议的动态成员分区可以最大限度地减少投票人错误输出的出现次数。对三模冗余(TMR)容错系统的投票器进行了仿真,结果表明,与现有算法相比,该算法具有更好的安全性和可用性。然而,我们的投票人设计是通用的,因此它可能有助于提高关键容错系统的安全性和可用性。
