Abstract :
The purpose of this work is to present a new approach for stabilizing single-input nonlinear systems for which the robust relative degree equals the dimension of the state space. In contrast to the approach used in approximate feedback linearization, we employ piecewise constant controllers. This allows us to obtain exact feedback linearization at the sample times, and approximate feedback linearization between samples.
