We study the class of nonlinear dynamical systems which vector field is defined by polynomial functions. A large set of systems can be modeled using such class of functions. Tests for stability are formulated as semidefinite programming problems by considering positive polinomials to belong to the class of Sum of Squares polynomials. Polynomial control law gains are computed based on a linear change of coordinates and guarantee the local stability of the closed-loop system. Lyapunov theory is then applied in order to obtain estimates of the region of attraction for stable equilibrium points. Such estimates are given by level sets of polynomial positive functions.La classe des systèmes non-linéaires dont la dynamique est définie par un champ...
