Linear and nonlinear modelling for fault detection and identification
E. Simeu1, T. Herve1

The input-output maps of nonlinear systems are approximated with linear in parameter polynomial different equations. In both the linear and nonlinear cases, simple least-square algorithms are used for reference nominal system characterisation and for actual system parameter estimation. An asymptotic approach for change detection based on parameter deviation monitoring via a data-to-model distance is presented.
