Based on tang design of a multi-scroll chaotic attractor model using a simple sinusoidal function, firstly, a basic dynamic analysis has been carried out of the system, with the stability of the equilibrium point determined according to the eigenvalues calculated by Jacobian matrix corresponding to each equilibrium point, followed by an analysis of the dissipation of the system by using the phase space volume change rate. Secondly, a numerical simulation analysis of the system can be made by using Lyapunov exponent, dimension and Poincare section diagram, with a tentative inquiry into the influence of different parameters on the basic dynamic characteristics of the system, thus providing a theoretical basis for the reasonable selection of system parameters.
