Real Time Controller Design by Using Wireless Sensor Actuator Networks Amirhosein Golfar a golfar@ec iut ac ir Date of Submission 2011 10 18 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor J Ghaisari ghaisari@cc iut ac ir Abstract Using wireless networks instead of point to point wiring has attracted attention in recent years Wireless networks application has been extended for Data Aggregation and process monitoring in manyresearches and industrial applications and is known as Wireless Sensor Network WSN Nowadays Wireless Sensor Actuator Network WSAN has been presented to extend WSN to control applicationswith Real Time loop WSAN provides a structure for implementation of networked control system usingwireless technology Aside from the advantages such as decrease in wiring costs facility in installing andmaintenance increase in scalability possibility of monitoring and controlling in hazardous area andpossibility of controlling geographically distributed systems It has some challenging area such as delays andpacket loss in transferring data packet congestion in networks synchronization of different part of thecontrol system requirements of real time controller information security and reliability Among thesechallenging problems delay and packet loss are considered more by control researchers In this dissertation resolving the real time controllers problems using WSAN is studied WSANs hastwo main objectives transmission of observations and sensor measurements to the controller through sensor side network and forwarding control commands of controller to the actuators through actuator side network To reach the first goal an optimal estimator is proposed This estimator is compatible with the constraints ofsensor side network and has the ability of real time estimating in the presence of delays packet loss multi sensor structure and out of order data reception To reach the second goal a centralized controller isdesigned and the control loop of WSAN is completed All the information and observations from all thesensors actuators and networks condition are sent to the centralized controllers and this controller calculatesthe control commands and sends them to the actuators via wireless network Key Words Networked Control System NCS Wireless Sensor Actuator Network WSAN Networked Estimator Networked Controller Optimal Tracker Compensate Delay and Packet Loss
