Visualizing Non-linear Ordinary Differential Dynamic System Using Simulink

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.
