文摘

Hybrid BG extends the ability of BG to model switched systems using intuitive representation for structural discontinuities. HBG is used as a unified tool for a combination of Quantitative-Qualitative FDI appraoch that numerically evaluate residual signals Qualitative Trend Analysis and Page Hinkley Test are used for a real time symbolic signature estimation of residual signals Causal Graph deduced from HBG and parameterized by the state of the controlled junction is used for symbolic prediction.
