A DATA-DRIVEN MULTIDIMENSIONAL VISUALIZATION TECHNIQUE FOR PROCESS FAULT DETECTION AND DIAGNOSIS(PPT)

摘要

1. PCA space is visualized through parallel coordinates. 2. Control limits established on PCs. 3. Run rules dictate fault detection performance 4. Detection performance better than classical approaches. 5. Unique signatures of faults in PC parallel coordinates facilitate fault identification. 6. Fault propagation analysis pending.
