The study of oscillation behavior and bifurcation mechanism of the switching circuit system is important for improving the performance of the circuit. In this paper, the oscillation behavior and bifurcation mechanism of a class of switching circuit system with nonlinear characteristics are analyzed and studied.Firstly, based on the system's motion equation and nonlinear characteristics, the mathematical model of the system is established and dynamic analysis is carried out. Through numerical simulation, periodic and chaotic solutions are found to exist in the system.Secondly, using bifurcation theory, the bifurcation phenomenon of the system under parameter changes is explored, and the bifurcation diagram of the system is obtained. On the basis of analyzing the bifurcation diagram, the phenomenon of double-period attractor and fractal structure of the system are further discussed.精品文档---下载后可任意编辑Finally, the oscillation behavior and bifurcation phenomenon of the system under different parameter conditions are compared, and the dynamic characteristics of the system are comprehensively analyzed.Keywords:Switching circuit; Oscillation behavior; Bifurcation mechanism; Bifurcation diagram; Periodic attractor; Fractal structure.
