Chaotification of a Spatiotemporal Coupled Map Lattice

Chaotification of a spatiotemporal coupled logistic-map lattice
via a state feedback control with a mod-operation is investigated.
A mathematically rigorous proof shows that the controlled system
satisfying certain parameter conditions is chaotic in the sense of
Li-Yorke and Devanay, respectively. Moreover, the chaotification
method is applicable to other coupled logisic-map lattices even
with different coupling modes. Simulation results have illustrated
the effects and verified the correctness of the theoretical
