This paper addresses the synchronization problem of systems modeled by EulerLagrange equations and subject to input saturations. First, a new control design strategy, based on virtual systems, is proposed. This approach allows to generate control inputs that are a priori bounded in the presence of communication time-delays, regardless of the information flow topology between systems in the netw...

A giant forging hydraulic press active synchronous control system is a mutually-coupled multi-input and multi-output system. To solve the elimination of the multi-channel interference, a multiple-input and multiple-output mathematical model center on active-beam is established; multi-channel synchronous decoupling control strategy is studied. The simulation results show that: the system elimina...

In this paper a control strategy based on Energy Shaping is designed for the nonlinear boost DC-AC converter with no-resistive load. This approach does not need to use any reference signal. A Phase-Locked Loop is added to the control law in order to achieve synchronization between the two parts of the circuit, which is necessary to obtain the desired output voltage. It is also shown that this i...

In this study, we propose a secure communication scheme based on the synchronization of two identical fractional-order chaotic systems. The fractional-order derivative is in Caputo sense, and for synchronization, we use a robust sliding-mode control scheme. The designed sliding surface is taken simply due to using special technic for fractional-order systems. Also, unlike most manuscripts, the ...

Clock distribution networks synchronize the flow of data in digital systems, and the features of the clock signal affect system performance and reliability. The great advances in integration levels and speed requirements in actual digital systems lead to enormous complexity in synchronization. Differences in delay of clock signals along clock paths, due to different lengths or active elements s...

this paper is concerned with the problem of synchronization for complex dynamic networks with state and coupling time-delays. therefore, larger class and more complicated complex dynamic networks can be considered for the synchronization problem. based on the lyapunov-krasovskii functional, a delay-independent criterion is obtained and formulated in the form of linear matrix inequalities (lmis)...

In Model-Driven Engineering, bidirectional transformations are key to managing consistency and synchronization of related models. Deltalenses are a flexible algebraic framework designed for specifying deltabased synchronization operations. Since model consistency is usually not a one-to-one correspondence, the synchronization process is inherently ambiguous, and consistency restoration can be a...

Most approaches to control-unit optimization use a finite state machine model, where operations are bound to control states. However, when synthesizing circuits from a higher, more abstract level of hardware specification that supports concurrency and synchronization, these approaches may be overly restrictive. We present a strategy for optimizing control circuits based on resynchronization of ...
