Generation of $n\times m$-Wing Lorenz-Like Attractors From a Modified Shimizu–Morioka Model

This paper explores the generation of n- and n times m-wing Lorenz-type attractors from a modified Shimizu-Morioka system. The basic idea is to increase the number of index-2 equilibrium points by introducing a multisegment quadratic function and a stair function in the 2-D state-space of the system. The design is verified by both simulation and experiment, where multiwing attractors over a grid can be clearly observed.
