摘要:

针对实际工程系统中控制器输入易受动态饱和与延时动态饱和约束,导致复杂动态网络拓扑辨识难以适配真实物理场景的问题,提出一种基于驱动-响应机制的拓扑辨识方法。构建与原网络动力学特性及节点规模相同的响应网络,建立驱动-响应网络间的同步误差动力学方程;设计含动态饱和与延时动态饱和的控制器及拓扑辨识器,利用Lyapunov稳定性方法推导误差系统稳定的充分条件,实现驱动-响应网络外同步,进而精确辨识原网络拓扑结构。数值仿真结果验证了所提方法的有效性。

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
