Brief Universal stabilization of feedforward nonlinear systems

In recent years, many important results on global stabilization of feedforward nonlinear systems have been proposed. However, in all previous results, to develop a global stabilizer, one must know some a priori information on system nonlinearities. For example, it is required that the system nonlinearities be known, or be bounded by known functions, or be linearly parametrized, or satisfy some high order growth rate condition, etc. The contribution of this paper is proposing a universal global stabilizer design for a class of feedforward systems, which does not require a priori knowledge of system nonlinearities.
