2. 21. Management control for sustainability : Activities and procedures for energy management in industrial companies

   Author : Josefine Rasmussen; Mikael Ottosson; Henrik Nehler; Fredrik Tell; Fredrik Nilsson; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability management control; energy management; energy efficiency investments; decision-making; activities and procedures; non-energy benefits; energy-intensive industries; Energiledning; investeringar i energieffektivisering; styrning; beslutsfattande; aktiviteter; procedurer; mervärden; energiintensiv industri;

   Abstract : The thesis takes its point of departure in the important role of the industrial sector in mitigating climate change through a reduced energy use. There is a lack of understanding for how energy management should be organised and implemented in industrial companies. READ MORE

4. 22. Design of Robust PID Controllers with Constrained Control Signal Activity

   Author : Olof Garpinger; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; measurement noise; constrained control signal activity; linear systems; disturbance rejection; PID control; process control; Youla parameterized controllers; algorithms and software;

   Abstract : This thesis presents a new method for design of PI and PID controllers with the level of control signal activity taken into consideration. The main reason why the D-part is often disabled in industrial control loops is because it leads to control signal sensitivity of measurement noise. READ MORE

5. 23. Multivariable Frequency-Domain Identification of Industrial Robots

   Author : Erik Wernholt; Svante Gunnarsson; Jan Swevers; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency-domain identification; industrial robots; nonparametric identification; nonlinear gray-box identification; multivariable systems; closed-loop identification; Automatic control; Reglerteknik;

   Abstract : Industrirobotar är idag en väsentlig del i tillverkningsindustrin där de bland annat används för att minska kostnader, öka produktivitet och kvalitet och ersätta människor i farliga eller slitsamma uppgifter. Höga krav på noggrannhet och snabbhet hos robotens rörelser innebär också höga krav på de matematiska modeller som ligger till grund för robotens styrsystem. READ MORE

6. 24. Attack Resilient Cloud-based Industrial Control Systems

   Author : Fatemeh Akbarian; Bredbandskommunikation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Industrial control systems (ICSs) are a significant part of industry and they play an important role in monitoring and controlling industrial processes. Traditionally, ICSs have been isolated from the Internet, and thereby secured from various Internet-based security threats. READ MORE

7. 25. On Model Libraries for Thermo-hydraulic Applications

   Author : Jonas Eborn; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; simulation; Matematik; Automation; Termisk teknik; control systems; nonlinear models; parameter estimation; proces s control; thermo-hydraulic systems; model validation; Thermal engineering; applied thermodynamics; termodynamik; Automatiska system; robotics; control engineering; reglerteknik; robotteknik; Mathematics; object-oriented;

   Abstract : Mathematical modelling and simulation are important tools when dealing with engineering systems that today are becoming increasingly more complex. Tightly integrated production and process optimization are trends that give rise to heterogeneous systems, which are difficult to handle without expertise in several engineering disciplines. READ MORE
