Abstract :
There are several results about global stabilization of a class of nonlinear systems with triangular or feedforward conditions. However, existing results are only applicable to an uncertain systems assumed to be known whether the the structure of nonlinearity is triangular or feedforward. In this paper, we propose an adaptively switching scheme for the output feedback system which can tune the gain dynamics online without a priori knowledge of the nonlinearity´s structure.
