잡음이 존재하는 선형 시스템에서의 센서 고장감지에 대한 연구

A study on the sensor failure detection and diagnosis in the stochastic system

In the paper a failure detection and diagnosis method of a stochastic system is proposed. It is based on the comparison of the moving averages generated from outputs of the real plant and a modeled normal plant. The proposed method allows us to locate the failed sensor and can be efficiently used for the failure detection and diagnosis of a plant with many sensors.
