Abstract :
The paper concerns adaptive estimation of dynamic systems which are nonlinearly parametrized. A majority of adaptive algorithms employ a gradient approach to determine the direction of adjustment, which do not suffice for estimation in systems with nonlinear parametrization. We introduce a new algorithm which employs a different regression vector and leads to globally stable estimation
