Implementation of Networked Control Systems using TCP/IP

This paper provides a general framework of Networked Control Systems. An Internet based NCS is simulated and TCP/IP communication issue of data streams in Networked Control Systems (NCS) is evaluated. The network is simulated with the ns-2 package, a widespread state-of-the-art open-source network simulator package for studying packet dynamics in networks. The ns-2 release is extended in order to simulate the transmissions of plants and controllers that are modelled by ODEs (solved via a linked package).The results show the overall control and network performances achieved while modelling the individual control and network components. The performance results of different types of data streams in NCS are also presented. Stability issues of NCS are being explored.
