Applications of Fault Detection Methods to Industrial Processes
نویسنده
چکیده
Components of industrial processes are often affected by un-permitted or un-expected deviations from normal operation behaviour. The fault detection task consists of determination of the fault present in a system and the time of detection. In addition to fault detection follows the fault identification by determination of kind, location and time of detection of a fault. These procedures are based on the observed analytical and the heuristic knowledge of the process. In this paper a comparison between different methods of fault detection and some examples of the fault detection and identification procedure for industrial processes is provided. For some classes of processes the structure and some parameters are well known but for others only rough models are available. Therefore the methods for fault detection and diagnosis are mainly different. Key-Words: Fault Detection and Diagnosis, Industrial Processes, Symptoms, Residuals

In this study, detection and identification of common faults in industrial gas turbines is investigated. We propose a model-based robust fault detection(FD) method based on multiple models. For residual generation a bank of Local Linear Neuro-Fuzzy (LLNF) models is used. Moreover, in fault detection step, a passive approach based on adaptive threshold is employed. To achieve this purpose, the a...
