Synchronization behavior is one of the most important characteristics of system. However, in practice, it is impossible to know all the system parameters, which increases the difficulty of network synchronization control. Thus, a controller is designed to achieve network synchronization based on the pinning control method, the extended state observer theory and the backstepping sliding mode control method. First, an extended state observer is designed to observe the uncertain variables. Second, a pinning controller is designed to realize network synchronization based on the backstepping sliding mode control. Finally, the simulation of a random 30-node Lorenz chaotic network verifies the correctness of this method.
