16. Security Analysis of a Wireless Quadruple Tank Control System
L3-uppsats, KTH/ReglerteknikSammanfattning : The main emphasis of this Master Thesis is the analysis of the effect of malicious deception attacks applied to a real process, in this case a scale model of a water distribution system made up of four interconnected water tanks and two pumps to control the water levels. The process model is derived, followed by the design and est of three kinds of controllers: LQG, PI and PI robustified with the Glover-McFarlane method. LÄS MER
17. Stochastic Estimation and Control over WirelessHART Networks: Theory and Implementation
Master-uppsats, KTH/ReglerteknikSammanfattning : There is currently a high interest of replacing traditional wired networks with wireless technology. Wireless communications can provide several advantages for process industries with aspect to exibility, maintenance and installation. LÄS MER
18. Implementering av multivariabel reglering i DCS-miljö
Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknikSammanfattning : Inom processindustrin finns en etablerad reglerhierarki där basreglering sker med PID-regulatorer och där avancerad, multivariabel styrning sköts av MPC-programvara. Steget mellan dessa två nivåer kan upplevas som stort. För mindre och snabba multivariabla processer undvikes helst en multivariabel ansats, med försämrad reglering som följd. LÄS MER
19. Reglering av en isoterm kalorimeter
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : Within many scientific areas there is interest in finding out the amount of energy turning to heat within different processes. One of the most common examples are cement hydration, where the heat emission leads to information about cement qualities like reaction speed and strength increase. LÄS MER
20. Modeling and Control of Reaction Calorimeter System
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : In dealing with calorimetry, safety aspects are very important. It is therefore very useful to be able to study a process before carrying out experiments on it. A computer model can then be very useful to save time and money. LÄS MER
