This paper proposes a novel approach for generating a multi-scroll chaotic system.Together with the theoretical design and numerical simulations,three different types of attractor are available,governed by constructing triangular wave,sawtooth wave and hysteresis sequence.The presented new multi-scroll chaotic system is different from the classical multi-scroll chaotic Chua system in dimensionless state equations,nonlinear functions and maximum Lyapunov exponents.In addition,the basic dynamical behaviours,including equilibrium points,eigenvalues,eigenvectors,eigenplanes,bifurcation diagrams and Lyapunov exponents,are further investigated.The success of the design is illustrated by both numerical simulations and circuit experiments.
