In order to completely characterize an asymptotically stable equilibrium point, some information about the size and shape of its Domain of Attraction is required. In this contribution a global optimization approach is proposed to estimate domains of attraction of general nonlinear dynamic systems. The technique is illustrated by a two states system that presents a very rich nonlinear behavior and is then applied to a typical continuous stirred tank reactor.
