Abstract

It is very important to research non-linear ordinary differential dynamic systems (DDS) by using numerical and visualizing methods. In this paper, taking the famous Duffing's equation as an example, we introduce some visualization skills for visualizing the non-linear DDS based on the Simulink platform. We present a set of rendering methods for phase diagram, Poincare's mapping, bifurcation graph, correlative dimension of chaotic attractors, etc. The methods and skills presented in the paper can be used in analyzing various non-linear DDS.
