Abstract

We consider the simplest design problem for nonlinear systems: the problem of rendering asymptotically stable a given equilibrium by means of state feedback. For such a problem, we provide a necessary condition, known as Brockett condition, and a sufficient condition, which relies upon the definition of a class of functions, known as control Lyapunov functions. The theory is illustrated by means of a few examples. In addition, we discuss a nonlinear enhancement of the so-called separation principle for stabilization by means of partial state information.
