Abstract:

In view of the problem that the controller inputs in actual engineering systems are vulnerable to the constraints of dynamical saturation and delayed dynamical saturation, which makes it difficult for the topology identification of complex dynamical networks to adapt to real physical scenarios, a topology identification method based on the drive-response mechanism was proposed. A response network with the same dynamical characteristics and node scale as the original network was constructed, and the dynamical equation of synchronization error between the drive-response networks was established. A controller with dynamical saturation and delayed dynamical saturation and a topology identifier were designed, and sufficient conditions for the stability of the error system were derived using the Lyapunov stability method to achieve the outer synchronization of the drive-response networks, thereby accurately identifying the topology structure of the original network. Numerical simulation results verify the effectiveness of the proposed method.

Key words: complex dynamical network, topology identification, drive-response network, dynamical saturation, delayed dynamical saturation
