摘要:
In this paper, a new approach is developed for the detection of malfunctioning sensors for large-scale linear interconnected dynamical systems. The main idea used is to do an overlapping decomposition in order to design multiple decentralised observers. Differences between the same state as estimated by the different observers can be used to isolate the malfunctioning sensors. A sixth-order ladder network example is used to illustrate the approach.
