... diagnosis approach for a class of nonlinear systems has been analyzed. The approach combines the use of a diagnostic observer with an adaptive fault estimation technique, which makes use of a parametric model. Convergence analysis of the resulting adaptive estimation scheme has been carried out by using...

...Yongliang Zhu; Prabhakar R. Pagilla Adaptive estimation of time-varying parameters in linearly parametrized systems is considered. The estimation time is divided into small intervals; in each interval the time-varying parameter is approximated by a time polynomial with unknown coefficients...
