It proposes an approach for constructing and generating grid multi-wing piecewise-linear hyperchaotic systems via sign function switching and super-heteroclinic loop. Take the Lorenz system for example. The related system was linearized at its equilibrium points
and a linear feedback controller was introduced. According to sign function switching control
the super-heteroclinic loop connecting the equilibrium points was found. By shifting transformation
grid multi-wing hyperchaotic Lorenz attractors were then formed. The theoretical analysis and numerical simulation have demonstrated the feasibility and effectiveness of this method.
