Distributed systems consist of multiple processors which corporate with one another by sending messages over communication networks. These communication networks often have transmission delay which results in a physical and logical function of geographical distance, communication bandwidth, and communication protocol overhead. The delay essentially characterizes distributed systems and one of t...

Future Distributed Power Grid (DPG) control systems may strongly benefit from the introduction of a communication network enabling cooperation between distributed generators. However, this typically comes at the cost that network induced time delay deteriorates control performance and possibly destabilizes the overall system. In this paper we study the effect of the time delay on the performanc...

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...

In this paper, robust finite-time consensus of a group nonlinear multi-agent systems in the presence communication time delays is considered. particular, appropriate delay-dependent strategies which are less conservative suggested. Sufficient conditions for deterministic and stochastic disturbances presented. The don’t need to be invariant, uniform, symmetric, or even known. only required condi...

priority queues have a great importance in the study of computer communication networks in which different types of traffic require different quality of service standards. the discrete-time non-preemptive priority queuing model with priority jumps is proposed in this paper. on the basis of probability generating functions mean system contents and mean queuing delay characteristics are obtained....
