This chapter examines methods for generating multiscroll chaotic attractors from nonautonomous systems. Basic techniques include using a pulse-driven oscillator based on Chua’s circuit and a multi-level logic pulse excitation scheme, which generate multi-double-scroll attractors without altering the original nonlinear functions. The task is performed using Chua’s circuit, a jerk circuit and a modified Lorenz system, highlighting the scalability and versatility of the methods. PSpice simulations verify and demonstrate these methods, confirming their effectiveness in circuit implementation. Additionally, a 4-D autonomous chaotic system is introduced, which can generate coexisting butterfly-like attractors. These findings enhance the understanding and design of nonautonomous chaotic systems towards engineering and scientific applications.
