Chaos induction using a reference model assisted control

A stable period two orbit in the parametric vicinity of a chaotic attractor is prevented from being reached, via the exclusion of trajectories from its near vicinity using a reference model based control strategy. This results in the inception of sustained chaotic dynamics. The reference model control strategy includes a predictive term enabling delimitation of precluded zones for the system dynamics. This technique for promotion of chaotic behavior is illustrated by using an experimental electrochemical cell involving the potentiostatic electro-dissolution of copper in phosphoric acid.
