This manuscript deals with a new insight into multi-switching combination–combination synchronization among different chaotic systems for fully unknown parameters. The suitable controllers and parameter update laws are designed by employing adaptive control and Lyapunov stability approach, to achieve asymptotically stable synchronization states for two drive and two response systems. In order to demonstrate the proposed methodology, an example of Lorenz system, Lu system, Chen–Lee system and Wang system is considered where Lorenz system and Lu system are taken as drive systems and Chen–Lee system and Wang system are taken as response systems. Numerical results are performed to justify the theoretical approach. Computational and theoretical results are in excellent agreement.
