액체 수송계에 대한 고장 검출 진단시스템의 설계 = Design of a Fault Detection and Isolation System for a Liquid Transprotation System

다국어 초록 (Multilingual Abstract)

In this study, a fault detection and isolation system(FDIS) is constructed for the supervision of the liquid transportation system that is composed of DC-motor, centrifugal pump and pipe-lines. The FDIS consists of the residual generator, detection logic and fault isolation logic and it can be classified as the dedicated observer scheme(DOS). The system can detect the occurrence of sensor faults and identify the failed, sensor. And the process faults that may occurr in the components such as DC-motor, centrifugal pump and pipe-lines can be promptly detected and diagnosed with the FDIS. It may provide an effective way that will enhance the safety and the functional reliability of the fluid transportation systems.
