报告摘要：

    This lecture shall review how methods for asymptotic stabilization of nonlinear systems have evolved during the last five decades. The emphasis is on the design of feedback laws yielding asymptotic stability of an equilibrium, either globally or -- at least -- with a guaranteed domain of attraction. Beginning with elementary methods based on reduction to a linear system, the lecture shows how the notions of normal form, zero dynamics and output-to-input stability have played a fundamental role in  the design of state-feedback stabilizing laws for single-input single output systems. Examples and counterexamples illustrate various key issues. Then, the lecture addresses also the problem of stabilization by dynamic output feedback and a nonlinear version of the so-called separation principle is presented. The issue of robustness with respect to model uncertainties is addressed by means of the so-called extended observer. Finally, a short overview of how the problem can be addressed for multi-input systems is given.
