摘要: In this paper, a geometric approach to fault detection and isolation (FDI) is applied Multiple-Input Multiple-Output (MIMO) model of frame the FDI results are compared ones obtained in Single-Input Single-Output (SISO), (MISO), (SIMO) cases. A proper distance function based on parameters from parametric system identification method used approach. ARX (Auto Regressive with eXogenous input) VARX (Vector ARX) models 12 all above-mentioned models. The reveal that by increasing number inputs, classification errors reduce, even case applying only one inputs computations. Furthermore, measured outputs scheme decreasing errors. Also, it shown using probabilistic space function, diagnosis has better performance comparison deterministic one.
