예측 기법을 이용한 drive-by-wire 시스템의 결함 허용 시스템 개발

As many systems depend on electronics, concern for fault tolerance is growing rapidly. For example, a car with its steering controlled by electronics and no mechanical linkage from steering wheel to front tires (steer-by-wire) should be fault tolerant because a failure can come without any warning and its effect is devastating. In order to make system fault tolerant, there has been a body of research mainly from aerospace field. This paper presents the prediction based fault tolerant structure that can remove most erroneous values. In addition, several numerical simulation results are given where the suggested system outperforms well-known average and median voters.
