“…A repetitive control was designed to address periodic disturbances caused by rotating components [10]. To overcome the influences of disturbance on the tracking performance, a feedforward control and an observer-based sliding model control were proposed in Kang et al [19] and Nian et al [20], respectively. Since H ∞ control can provide the minimized output errors when control systems suffer from "the worst" disturbances, H ∞ syntheses have strong robustness to external disturbances [21].…”

In this paper, a decentralized guaranteed cost H ∞ control strategy is proposed for large-scale web-winding systems with uncertain and time-varying parameters. First, the large-scale web-winding system is viewed as a synthetic system composed of several dynamic subsystems, and interval matrix is used to deal with parameter uncertainties and the changes of set point. Second, a decentralized guaranteed cost control (DGCC) is developed to achieve the track goal, and guarantees that a cost function defined for the control system has an upper bound. Furthermore, an optimal DGCC (ODGCC) is designed to minimize the upper bound. Third, H ∞ control strategy is incorporated in the DGCC to increase closed-loop system robustness to parameter uncertainties and external disturbances. Finally, some simulation and experiments are performed on a three-motor web-winding system to verify the effectiveness of the presented control methods.

“…For instance, in industrial web-winding systems, if the motors and the webs between motors are abstracted as nodes and edges, respectively, the motor speed and web tension can be regarded as state variables. A dynamic system of the webs' tension (i.e., the edges' states) can be established based on actual production equipment, and an underactuated control method for motors can be used to make the web tension reach the target value [18,19]. A web-winding system is a typical complex system with dynamic edges, where the coupling relationship between the states of nodes and edges is the source of complex dynamic behavior.…”

The scope of complex dynamical networks (CDNs) with dynamic edges is very wide, as it is composed of a class of realistic networks including web-winding systems, communication networks, neural networks, etc. However, a classic research topic in CDNs, the synchronization control problem, has not been effectively solved for CDNs with dynamic edges. This paper will investigate the emergence mechanism of synchronization from the perspective of large-scale systems. Firstly, a CDN with dynamic edges is conceptualized as an interconnected coupled system composed of an edge subsystem (ES) and a node subsystem (NS). Then, based on the proposed improved directed matrix ES model and expanded matrix inequality, this paper overcomes the limitations of coupling term design in node models and the strong correlation of tracking targets between nodes and edges. Due to the effect of the synthesized node controller and the auxiliary effect of the ES, state synchronization can be realized in the CDN. Finally, through simulation examples, the validity and advantages of our work compared to existing methods are demonstrated.

“…The corresponding phenomena also occurs in many real networks. For example, in the multi‐motor web‐winding systems, 23‐25 the velocities variations of roller (nodes) are caused by the change of web (links) tension between the roller and adjacent roller. The power variations of generators or substations (nodes) are caused by the wave of the transmission line (links) power in the electric power grid 6,7 .…”

Along with the numerous highly interconnected nodes in real networks, a complex dynamical network shows the dynamic behaviors not only in the nodes but also in the links between nodes. This implies that the complex dynamical network can be considered to be composed of the two interconnected subsystems, the nodes subsystem (NS) and links subsystem (LS), and thus it has become evident that the dynamics of LS plays an important role in assisting NS to emerge the dynamic behavior. However, all the dynamic links are rarely considered to be the dynamic system as a whole in the existing literature. In this article, the outgoing links vector is introduced to describe the state of LS and the dynamics of LS is proposed and utilized to investigate the tracking task of NS. Here, the bounded uncertainties are considered in the dynamic model of NS and the nonlinearities are considered in the dynamic model of LS, which is rarely considered in the existing literature, by which the adaptive controller is synthesized to overcome the uncertainties and complete the tracking task of NS assisted with the constructed coupling term in LS. The results in this article show that when the controlled NS is tracking the given target, the LS is tracking the proposed auxiliary target. Finally, the effectiveness of the proposed theoretic results is verified via the example. K E Y W O R D Sadaptive tracking control, complex dynamical network with uncertainties and nonlinearities, the links subsystem, the nodes subsystem, the outgoing links dynamics INTRODUCTIONIn the last decades, the study of complex dynamical network mainly focuses on the structure and function of network, especially, how the links topology between nodes can effectively assist all the nodes to track the given reference signals, which has attracted extensive attention from many scholars. The complex dynamical network has been widely employed to describe many real networks such as the food webs, 1 the wireless sensor network, 2,3 the brain network, 4,5 the electrical power grids, 6,7 World-Wide Web, 8 and so on. It is remarkable that these studies as reviewed in References 9-15 only focus on the collective behavior of nodes such as synchronization, nevertheless, the all the links are regarded only as playing the auxiliary and secondary role for all the nodes tending synchronization. In order words, the dynamics of links in the complex dynamical network should be transformed into an independent dynamical subsystem and their dynamics should be considered as reviewed in References 16-22.
