This chapter introduces some methodologies for generating hyperchaotic multiscroll attractors from various systems. The techniques include modifying a 4-D Chua’s circuit, the MCK circuit, CNNs, and coupled Chua’s circuits with sine functions. The chapter also highlights the extension of PWL functions to create \(n\) -scroll chaotic attractors and investigates higher-dimensional grid-scroll hyperchaotic attractors. Theoretical models presented in the chapter are supported by experimental simulations, demonstrating their feasibility and potential applications to engineering and nonlinear dynamics research.
