| Abstract: | A strategy based
on principal component analysis (PCA) is presented for detection,
identification and reconstruction of faulty sensors. In this strategy, sensor
fault detection is carried out by using multivariate statistics, faulty sensors
are isolated using principal component score contributions and reconstruction
of faulty sensors is accomplished through the analysis of fault direction
vector. The performance of the strategy is evaluated by applying to a
closed-loop controlled CSTR system. The simulation results demonstrate the
ability of the strategy for detection, identification and reconstruction of
single and multiple faulty sensors. |
