Yet another algorithm for chaotifying control of discrete chaos (Q2705735)

This paper is devoted to a feedback control algorithm for chaotification of an originally non-chaotic system. Here the discontinuous modulus function is replaced by a continuous sawtooth function which still ``folds'' the trajectories back into the original phase space area, but that is easier to reproduce in a circuit. The authors apply the Marotto theorem to prove that the modified Chen-Lai feedback anticontrol methods yield chaos in the sense of Li and Yorke.
