Complete synchronization (CS) can occur in non-identical chaotic systems by adjusting coupling, and generalized synchronization (GS) in identical systems. This research offers a new method for robust CS in chaos communications.

Area of Science:

  • Nonlinear dynamics
  • Chaos theory
  • Synchronization phenomena

Background:

  • Complete synchronization (CS) is typically associated with identical chaotic systems.
  • Generalized synchronization (GS) is considered an extension for non-identical systems.
  • The influence of coupling strategies on synchronization types is often overlooked.

Purpose of the Study:

  • To investigate the role of coupling strategies in determining synchronization types.
  • To demonstrate that CS can be achieved in non-identical chaotic systems.
  • To show that GS can be achieved in identical chaotic systems.

Main Methods:

  • Numerical simulations of coupled chaotic systems.
  • Analysis of different coupling strategies.

  • Experimental verification using electronic circuits.

    • Main Results:

    • Complete synchronization (CS) was observed in coupled chaotic systems with parameter mismatch through specific coupling strategies.
    • Generalized synchronization (GS) was achieved in coupled identical chaotic systems.
    • Numerical findings were supported by experimental results from electronic circuits.

    Conclusions:

    • The type of synchronization (CS or GS) is significantly influenced by the coupling strategy, not solely by system identity.
    • A novel method for achieving robust CS in synchronization-based chaos communications is presented.
    • This work challenges conventional views on synchronization in chaotic systems.
