In this paper, the synchronization problem for dynamical complex networks composed of general Lur’e systems is dealt with. Based on the Jordan canonical transformation method and a Lur’e-Postnikov function, the global synchronization criteria for dynamical complex networks with non-symmetric coupling are established and formulated as LMI. A decentralized control strategy based on projection lem...

We present a novel hierarchical approach to cooperative control of multi-agent systems. The agents are modeled as non-identical nonlinear single-input single-output systems. The control strategy achieves synchronization of the agents to a common output trajectory of a desired type. It is based on synchronization of reference models on the network level and asymptotic model matching control on t...

The synchronization of chaotic rare-earth-doped fiber ring lasers is analyzed. The lasers are first coupled by transmitting a fraction c of the circulating electric field in the transmitter and injecting it into the optical cavity of the receiver. A coupling strategy which relies on modulation of the intensity of the light alone is also examined. Synchronization is studied as a function of the ...

In this work we address the problem of controlling a complex network toward a synchronous evolution by using pinning control strategy. Considering this control approach, we investigate the effect of the number of pinned nodes and how the strategy performance behaves in accordance with the type of nodes that are chosen as the ones over which the control is applied. The roles of the control and c...

We examine a specific strategy of using synchronization (sync) markers for error containment in compressed data, using a model that separates the data-compression and error-containment stages. We examine the trade-off between rate and error performance, determine classes of sync markers that give equivalent performance, and examine the optimum choice of sync marker and data block length. The pe...

During the last few years, new synchronization techniques to send data between IC’s at increasingly high datarates have been developed. Some of them rely on digital delay lines. The timing accuracy of the delay lines is crucial for a good functionality of the synchronization mechanism. This paper will present a strategy to measure the tap-delays of a digital delay-line, using the well-known osc...

Synchronization in chaotic systems has become an active area of research since the pioneering work of Pecora and Carroll. Most existing works, however, rely on a passive approach: A coupling between chaotic systems is necessary for their mutual synchronization. We describe here a feedback approach for synchronizing chaotic systems that is applicable in high dimensions. We show how two chaotic s...

A new adaptive learning control approach is proposed for a class of nonlinearly parameterized complex dynamical networks with unknown time-varying parameters. By using the parameter separation and reparameterization technique, the adaptive learning laws of periodically timevarying and constant parameters and an adaptive control strategy are designed to ensure the asymptotic convergence of the s...

Abstract: In this study, the synchronization of the outputs for the uncertain chaotic systems with different-orders is presented. An adaptive fuzzy system has been used to approximate the uncertain nonlinear terms. The adaptive fuzzy control strategy is estimated to guarantee output-synchronization of the master-slave chaotic systems based on sliding control theorem. By using a dynamic compensa...

A new strategy of control is formulated for chaos synchronization of non-identical chaotic systems with different orders using the Borne and Gentina practical criterion associated with the Benrejeb canonical arrow form matrix, to drift the stability property of dynamic complex systems. The designed controller ensures that the state variables of controlled chaotic slave systems globally synchron...
