In this paper, the problem of exponential synchronization of Chaotic Lur'e systems with sampled-data control is investigated. It's noted that the sampling periods are arbitrarily varying and bounded. A novel Lyapunov functional is proposed which takes full advantage of the available information about the actual sampling patterns. A linear matrix inequality method is utilized to design the sampled-data...
This paper propose an asynchronous impulsive control scheme for consensus of second-order multi-agent systems. The proposed control scheme do not require time synchronization among agents. Each agents has its won clock to determine the impulsive instants. By using discretization approaches and the stochastic matrix theory, it is find that the stability of the proposed control scheme depends on the...
Synchronic-in-phase electric drive is widely used in thermal-imaging and laser scanning systems due to high accuracy characteristics in the wide range of angular speed regulation. The point of the article is to examine the application features of impulsive phase-frequency discriminator with extended functional abilities by implementation of different methods of electric drive control with phase synchronization...
This paper proposes the improvement method of operability in a bilateral control by using visual information. The bilateral control system consists of a master system which is manipulated by the operator and a slave system which contacts remove environment. Considering the actual use of the bilateral control, the operator manipulates the master system while watching the visual information from the...
The problem of synchronization of bilateral teleoperators in the presence of stochastic disturbances in control inputs is considered in this paper. It is clear that the mechanical systems are often subjected to random disturbances and it can influence the performance of the control system in an uncertain manner. To cope with this, the new adaptive controller is proposed. This technique uses the exponential...
This paper is concerned with the semi-global output synchronization problem of a heterogeneous network under event-triggered control mechanism. A distributed event-triggered scheme is proposed in this paper. The Zeno behavior can also be excluded in the designed scheme. By adopting the low-gain technique, it is shown that the input saturation nonlinearity can be avoided if the parameter of the parameterized...
With SDN increasingly becoming an enabling technology for NFV in the cloud, many virtualized network functions need to monitor the network state in order to function properly. An outdated network view at the controllers can impact the performance of those virtualized network functions. In earlier work, we identified two main factors contributing to an outdated network view in the case of a load-balancer:...
This paper investigates the consensus of multiagent systems with parameter uncertainty and control gain error. In order to decrease the communication cost, the impulsive consensus protocol is derived to achieve the consensus. Due to the inevitable disturbance, parameter uncertainty and control gain error in multi-agent systems are considered simultaneously. One necessary simulation is finally given...
In this paper, the control problems of the permanent magnet synchronous motor (PMSM) system are investigated extensively. Some single input controllers were proposed to realize the control problems of such system, such as stabilization, synchronization, coexistence of anti-synchronization and synchronization, projective synchronization. It is noted that there exist two different single input controllers...
Technology nowadays is growing very rapidly, so many systems have been digitized. Most of the digitization of this system leads to the development of web-based systems, it's also combined with embedded systems, to create a system called Web of Things. Besides, digitalization will be very useful if applied to the public service system, one of which is the queuing system. In this research, we are making...
This paper presents the performance analysis of visual feedback leader-following pose synchronization, where the leader motion is supposed to contain stochastic factors. Then, the problem is reformulated in stochastic system form and stochastic stability analyses are provided. Here, time evolution of the control error system produced by the present visual feedback control is given by stochastic differential...

Hence, there is a need of developing a scalable, flexible and reliable sensor network for related parameters monitoring. To install and replace water...
This paper is mainly concerned with the issues of two kinds of synchronization for a class of hyperchaotic systems, i.e., complete synchronization, and coexistence of synchronization and anti-synchronization. Two adaptive control laws with suitable state feedbacks are designed to realize the complete synchronization, and coexistence of synchronization and anti-synchronization for such hyperchaotic...

This paper discusses implementation of several fractional-order chaotic systems on different non-linear systems. Recently, the chaotic dynamic techniques such as chaos control and chaos synchronization have gained the attention of researchers. The real physical systems are inherently non-linear in nature and for such types of systems; chaos theory outperforms the analytical methods to solve the nonlinear...
State synchronisation in clustered Software Defined Networking controller deployments ensures that all instances of the controller have the same state information in order to provide redundancy. Current implementations of controllers use a strong consistency model, where configuration changes must be synchronised across a number of instances before they are applied on the network infrastructure. For...
For coordination and cooperation among the four motors in the same position of four manipulators, in order to make the manipulator motors have the precision and same speed, the double-layer control strategy is adopted in this paper. In the lower control, only the single mechanical arm motor can be stably controlled, the multiple manipulator motors can be synchronized. Therefore, fuzzy PID is used...
