A new method of controlling chemical chaos - Nonlinear artificial neural network (ANN)-occasional perturbation feedback control in the whole chaotic region

A new method of controlling chemical chaos to attain the stabilized unstabl e periodic orbit (UPO) is proposed. It is an extension of the occasional pr oportional feedback (OPF) control strategy which spans the limitations of O FF, i.e. the Linear region of the control rule, and extends to the whole ch aotic region. It also expresses the nonlinear control rule with the back pr opogation-artificial neural network (BP-ANN) in order to increase the robus tness of the control. Its effectiveness is examined through controlling an autocatalytic chaotic reaction model numerically.
