synchronization

The efficiency of operation of power units of powerful thermal and nuclear power plants is largely determined by the reliability of power supply systems for their own needs. The main requirements for such systems are maintaining the required voltage level on the busbars of the distribution charters of their own needs and reduction of the time of forced power outages. Ensuring these requirements by the Ukrainian energy sector is complicated by the fact that most of its power plants are operated for a long time, and their equipment is significantly worn out.

This paper deals with the problem of finite-time projective synchronization for a class of neutral-type complex-valued neural networks (CVNNs) with time-varying delays.  A simple state feedback control protocol is developed such that slave CVNNs  can be projective synchronized with the master system in finite time.  By employing inequalities technique and designing new Lyapunov--Krasovskii functionals, various novel and easily verifiable conditions are obtained to ensure the finite-time projective synchronization.  It is found that the settling time can be explicitly calculated for the neut

Synchronization of parallel processes of distributed information systems (DIS) has been largely determined by decisions taken at the stages of their design. Having already been in structural and functional models, when determining cause- and-effect relationships for events and actions in DIS components, it becomes necessary to coordinate them. In the proposed multilevel systemic, structural and functional synchronization model, a hierarchy of such causal relationships with interlevel mappings, inheritance and encapsulation of events and actions have been formed.
