Synchronization and Anti – Synchronization of Coupled Lorenz Chaotic Systems

In this work, partial contraction theory is proposed. With the help of nonlinear chaotic systems, virtual system is introduced. By making this system contracting, synchronization of coupled nonlinear chaotic systems is achieved. At the same time with the help of error addition method, anti-synchronization is also achievable.. Simulink’s results show that synchronization and anti-synchronization of nonlinear chaotic systems are well achieved.
