DES Approach Failure Diagnosis of Pump-valve System

펌프-밸브 시스템의 DES 접근론적 Failure Diagnosis

As many industrial systems become more complex, it becomes extremely difficult to diagnose the cause of failures. This paper presents a failure diagnosis approach based on discrete event system theory. In particular, the approach is a hybrid of event-based and state-based ones leading to a simpler failure diagnoser with supervisory control capability. The design procedure is presented along with a pump-valve system as an example.
