Highly comprehensive resource for studying neural networks, complex networks, synchronization, passivity, and associated applications

Dynamical Behaviors of Multiweighted Complex Network Systems discusses the dynamical behaviors of various multiweighted complex dynamical networks, with detailed insight on synchronization for directed and undirected complex networks (CNs) with multiple state or delayed state couplings subject to recoverable attacks, along with passivity and synchronization for coupled neural networks with multi-weights (CNNMWs) by virtue of devised proportional-integral-derivative (PID) controllers.

The book also investigates finite-time synchronization (FTS) and H-infinity synchronization for two types of coupled neural networks (CNNs) and focuses on finite-time passivity (FTP) and finite-time synchronization (FTS) for complex dynamical networks with multiple state/derivative couplings based on the proportional-derivative (PD) control method. Final chapters consider finite-time output synchronization and H-infinity output synchronization problems, and multiple weighted coupled reaction-diffusion neural networks (CRDNNs) with and without coupling delays.

Other topics covered in Dynamical Behaviors of Multiweighted Complex Network Systems include:

  • Criteria of FTP for complex dynamical networks with multiple state couplings (CDNMSCs), formulated by utilizing the PD controller
  • Finite-time passivity (FTP) concepts for the spatially and temporally systems with different dimensions of output and input
  • FTS and finite time H-infinity synchronization problems for CDNs with multiple state/derivative couplings by utilizing state feedback control approach and selecting suitable parameter adjustment schemes
  • Adaptive output synchronization and output synchronization of CDNs with multiple output or output derivative couplings, and other adaptive control schemes

Enabling readers to understand foundational concepts and grasp the latest research, Dynamical Behaviors of Multiweighted Complex Network Systems is essential for all who study neural networks, complex networks, synchronization, passivity, and their applications.

Preface

Recently, numerous researchers have turned their attention to the dynamical behaviors of complex dynamical networks (CDNs) including the synchronization, stability, and passivity. However, most of existing results on dynamical behaviors are all based on network models with single weight. It is well known that many real-world networks should be described by CDNs with multiweights, such as public traffic roads networks, social networks, intercity population flow networks, and so on. Therefore, it is meaningful to further study the dynamical behaviors for multiweighted CDNs (MWCDNs).

The purpose of this book is to introduce recent research work on analysis and control of dynamical behaviors for MWCDNs. The book is structured as follows:

Chapter 1 respectively takes the synchronization into consideration for directed and undirected complex networks (CNs) with multiple state or delayed state couplings subject to recoverable attacks. By employing inequality techniques, choosing appropriate Lyapunov functional, and adopting the designed state feedback controller, two criteria of the synchronization are developed for the directed CN with multiple state couplings (CNMSCs). Moreover, the synchronization of CNMSCs is also discussed for the case that the network topology is undirected. In addition, two types of CNs with multiple delayed state couplings are also proposed, and several criteria of synchronization are formulated for these networks.

Chapter 2 mainly discusses the passivity and synchronization for a coupled neural networks with multiweights (CNNMWs) by virtue of devised proportional-integral-derivative (PID) controllers. On the one hand, several passivity criteria for the CNNMWs are put forward on the basis of suitable Lyapunov functional, inequality techniques, and devised proportional-derivative (PD) controller, and the output-strict passivity is employed to deal with the synchronization of the CNNMWs. On the other hand, the passivity of the CNNMWs is also investigated by choosing appropriate proportional-integral (PI) controller, and a criterion of synchronization is developed for the CNNMWs.

Chapter 3 tackles the output synchronization problem for CDNs with multiple output or output derivative couplings in detail. With the help of inequality techniques and Lyapunov functionals, an output synchronization criterion is presented for CDNs with multiple output couplings (CDNMOCs). To ensure the output synchronization of CDNMOCs, an adaptive control scheme is also devised. Similarly, we also take into account the adaptive output synchronization and output synchronization of CDNs with multiple output derivative couplings.

Chapter 4 respectively focuses on finite-time passivity (FTP) and finite-time synchronization (FTS) for CDNs with multiple state/derivative couplings on the basis of PD control method. Several criteria of FTP for CDNs with multiple state couplings (CDNMSCs) are formulated by utilizing the PD controller and constructing an appropriate Lyapunov function. Furthermore, FTP is further used to investigate the FTS in CDNMSCs under the PD controller. In addition, the FTP and FTS for CDNs with multiple derivative couplings (CDNMDCs) are also studied by exploiting the PD control method and some inequality techniques.

Chapter 5 investigates the FTS and finite-time synchronization for two types of coupled neural networks (CNNs): the cases with multistate couplings and multiderivative couplings. By designing appropriate state feedback controllers and parameter adjustment strategies, some FTS and finite-time synchronization criteria for CNNs with multistate couplings are derived. In addition, the FTS and finite-time synchronization problems for CNNs with multiderivative couplings are further considered by employing state feedback control approach and selecting suitable parameter adjustment strategies.

Chapter 6 introduces two kinds of multiweighted and adaptive state coupled CNs with or without coupling delays. First, we develop the appropriate state feedback controller and adaptive law in order to guaranteeing that the proposed network models without coupling delays can be finite-time synchronized and synchronized. Furthermore, for the multiweighted CNs with coupling delays and adaptive state couplings, some finite-time synchronization and synchronization criteria are developed by choosing appropriate adaptive law and controllers.

Chapter 7 focuses the finite-time output synchronization and output synchronization problems for coupled neural networks with multiple output couplings (CNNMOCs), respectively. By choosing appropriate state feedback controllers, several finite-time output synchronization and output synchronization criteria are proposed for the CNNMOC. Moreover, a coupling-weight adjustment scheme is also developed to ensure the finite-time output synchronization and output synchronization of CNNMOC.

Chapter 8 introduces two kinds of multiple weighted coupled reaction-diffusion neural networks (CRDNNs) with and without coupling delays. On the one hand, some FTP concepts are proposed for the spatially and temporally system with different dimensions of output and input. By choosing appropriate Lyapunov functionals and controllers, several sufficient conditions are presented to ensure the FTP of these CRDNNs. On the other hand, the FTS problem is also discussed for the multiple weighted CRDNNs with and without coupling delays, respectively.

1Synchronization for Complex Networks with Multiple Weights Under Recoverable Attacks

1.1 Introduction

During the last decade, the dynamical behavior of complex networks (CNs) has aroused increasing attention because CNs prevalently exist in the real world. Particularly, synchronization has been an appealing research topic in CNs, and many meaningful results have been obtained [1–16]. By choosing appropriate adaptive state-feedback controllers and Lyapunov functional, Zhou et al. [1] discussed the global and local synchronization in a CN with uncertain coupling functions. In [4], the synchronization problem for a CN with switching disconnected topology was addressed, and some synchronization conditions were established for such a network model. Lv et al. [5] tackled the exponential synchronization problem for CNs with coupling delay based on the impulsive control and event-triggered control techniques. In [11], the synchronization problem for stochastic CNs was discussed via pinning control technique and graph theory, in which the topology structure may be unknown. Zhu et al. [14] used the adaptive control method to deal with the synchronization problem for a type of CNs with time-varying delay, in which the restriction that time delay is differentiable is removed.

For some practical networks, such as urban population flow networks, food webs, etc., may be better described by CNs with multiple weights (CNMWs). More recently, some authors have addressed the problem of synchronization for CNMWs [17–26]. Wang et al. [17] not only investigated the pinning synchronization in the CNMWs with undirected and directed topologies but also presented several feedback gains and coupling strengths adjustment schemes. In [18], a criterion of synchronization for output-strictly passive CNMWs was obtained, and the synchronization problem of CNMWs was further discussed based on the nodes- and edges-based pinning control approaches, and the output-strict passivity. Zhao et al. [23] introduced a multiple delayed CN model with uncertain inner coupling matrices and developed a criterion of synchronization through the adaptive control scheme for such a network model. Dong et al. [24] took into account the exponential synchronization of multiple delayed CNs with switching and fixed topologies by employing the scramblingness property for adjacency matrix. Qin et al. [26] analyzed the robust synchronization of multiple delayed CNs, and a criterion for guaranteeing the robust synchronization was also developed by employing the adaptive state-feedback controller.

It is well known that the network topology may be destroyed owing to the various forms of attacks (e.g., power grids, military communication networks, and so on [27–29]), which might lead to undesirable dynamical behavior in the CNs. Consequently, it is very meaningful to study the dynamical behavior for CNs under attacks. Recently, some researchers have studied the synchronization problem of CNs suffering the attacks [30,31]. Wang et al. [30] investigated the synchronization for multiple memristive neural networks with the communication links subject to attacks and developed several synchronization criteria based on inequality techniques, -matrix properties, and event-triggered control method. Wang et al. [31] gave a global synchronization criterion for a network model suffering the successful but recoverable attacks by exploiting the switching system theory and derived the upper bounds of the average recovering time and the attack frequency. Regretfully, the network models with single coupling were discussed in these existing works about the synchronization for CNs under attacks [30,31], and the synchronization for CNMWs subject to attacks has not yet been explored. Obviously, it is very valuable and significative to further address the synchronization problem of CNMWs suffering the attacks.

This chapter discusses the synchronization for CNs with multiple state couplings (CNMSCs) or CNs multiple delayed state couplings (CNMDSCs) under recoverable attacks, respectively. The main contributions of our work are summarized as follows. First, we not only give a sufficient condition for ensuring the synchronization of directed CNMSCs suffering the attacks but also further study the synchronization problem by selecting the suitable state-feedback controller. Second, the analysis and control for the synchronization problem of undirected CNMSCs subject to attacks are also discussed, and several synchronization criteria are presented based on some inequality techniques. Third, we not only develop several synchronization criteria for CNMDSCs under attacks by constructing appropriate Lyapunov functional but also devise the suitable state-feedback controller to ensure the network synchronization.
