We study the problem of semiglobally stabilizing a class of feedforward uncertain nonlinear system via measurement feedback. We improve the existing results in several directions: we allow for uncertain outputs and block state equations. Moreover, contrary to the classical literature, our procedure strongly relies on H infinity tools and backstepping, does not require any preliminary change of coordinates, ends up with a quadratic Lyapunov function for the closed-loop system and results in a nonsaturated linear controller.

Abstract
We study the problem of semiglobally stabilizing a class of feedforward uncertain nonlinear system via measurement feedback. We improve the existing results in several directions: we allow for uncertain outputs and block state equations. Moreover, contrary to the classical literature, our procedure strongly relies on H infinity tools and backstepping, does not require any preliminary change of coordinates, ends up with a quadratic Lyapunov function for the closed-loop system and results in a nonsaturated linear controller.
