This chapter explores advanced techniques for generating multiscroll chaotic attractors from some nonlinear dynamical systems. Various effective methods are introduced, including modifications to the modified Lorenz system, a chaotic system bridging the Lorenz and Chen systems, and a non-autonomous forced systems. Additionally, other generating methods are presented based on PWL van der Pol and Duffing systems, oscillatory potential wells and a thresholding mechanism. The chapter furthermore discusses innovative techniques for generating \(n \times m\) -grid chaotic attractors using arctangent function series. These methodologies for generating complex multiscroll attractors expand the application domain of chaos theory across engineering and technological fields.
