Multimodel identification and failure detection using neural networks (NN) is presented. It is an extension and application of nonlinear system identification using radial basis function NN. The state estimation error is proven to converge to zero asymptotically. Parameters of the identifier converge to the ideal parameters provided that persistency of excitation condition is fulfilled. Multiple model identification structure is analyzed, and its application to the multimodel failure detection is considered. Two simulation examples for NN identifiers are given. Simulation for intelligent multimodel failure detection using multi-neural networks identifiers is presented.
