Independent Component Analysis Based Fault Detection and Spatial Localization of Distributed Parameter Systems
Yun Wen Feng, Han‐Xiong Li · 2018
In this paper, a spatio/temporal separation based method is developed to detect fault and its spatial location for distributed parameter systems. Firstly, the original infinite-dimensional system is transformed into a finite-dimensional system by time/space separation and model reduction techniques. Then both independent component analysis and time/space synthesis methods are adopted to construct the monitoring model. Finally, experiments on a typical parabolic distributed parameter system are used to verify the effectiveness of the proposed approach.
