Dual phase synchronization of chaotic systems using nonlinear observer based technique

Abstract

The present paper reports an investigation on dual phase synchronization results among chaotic systems with nonlinear observer controller. The dual phase synchronization is achieved using the nonlinear state observer technique and the stability theory. The Qi system and the Newton-Leipnik system are considered during the demonstration of dual phase synchronization. The nonlinear state observer technique is found to be very effective and convenient to achieve dual phase synchronization of various types of chaotic systems. Numerical simulation and graphical results demonstrate the effectiveness of the control technique during dual phase synchronization among chaotic systems. © 2019 In for Math Publishing Group.
