abstract (eng):

Early recognition/isolation of a faulty behaviour of a dynamic system is presented. Fault detection and isolation methods based on adaptive probabilistic models with multiple modes represent a theoretically well justified way of solution.The complexity problem is addressed here by employing an efficient quasi-Bayes estimation algorithm. It is directly applicable to the mixture of components created as products of factors belonging to the exponential family. The theory is illustrated by a simulation example.
