Network Control System For DC Motor Using ANN

Abstract

Networked control systems (NCS) are distributed computing and control systems with sensors, actuators and controllers that communicate over a shared medium. The distributed nature of NCS and issues related to the shared communication medium pose significant challenges for control design, as the control system no longer follows the rules of classical control theory. The main problems that are not well covered by the traditional control theory are varying time delays and packet losses. The change of communication architecture introduces different forms of time delay uncertainty in the closed loop system dynamics. These time delays come from the time sharing of the communication medium as well as the computation time required for physical signal coding and communication processing. Moreover, the time delays in a control application can degrade a system’s performance and even cause system instability. In this Paper we have controlled the SPEED OF DC MOTOR using ANN Controller without Networked Control System and compare the result using ANN controller with Networked Control System with Plant Packet losses and controller signal losses using Sim Events Tool box. In this work Process with varying time delay and packet losses with ANN Controller is compared to plant without delay and packet losses. Main objective of this work is the use of Communication Network in a Process Control .
