2. 1. Perturbation-based Control of Industrial Fed-batch Bioprocesses

   Author : Ola Johnsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perturbation-based control; process control; fed-batch control; industrial bioprocesses;

   Abstract : The topic of this thesis is bioprocess control, more specifically control of industrial-scale microbial fed-batch bioprocesses. Its focus is therefore on methods which are easy to implement in an industrial setting, which gives certain limitations on sensors, actuators and control systems. READ MORE

4. 2. Resource-aware Wireless Process Control

   Author : Takuya Iwaki; Karl H. Johansson; Sophie Tarbouriech; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial process control; Networked control systems; Wireless network; Event-triggered control; Electrical Engineering; Elektro- och systemteknik;

   Abstract : To tackle the ever-growing demands on high-quality and cost-effective industrial production, recent developments in embedded sensing, wireless communication, and cloud computing offer great opportunities. Resource-aware reliable wireless communication and real-time control are needed to leverage these technologies. READ MORE

5. 3. Towards Improved Control of TMP Refining Processes

   Author : Karin Eriksson; Chalmers tekniska högskola; []

   Abstract : The need for improved energy usage has become a key issue in all industrial sectors. In the energy demanding production of mechanical pulps many efforts havefocused on design development, but regarding control of refiners, there is still a potential for improvements. READ MORE

6. 4. Nonlinear Identification and Control with Solar Energy Applications

   Author : Linda Brus; Bengt Carlsson; Torbjörn Wigren; Graham C. Goodwin; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedforward control; model predictive control; nonlinear control; nonlinear systems; recursive identification; solar power; system identification; time delay systems; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

   Abstract : Nonlinear systems occur in industrial processes, economical systems, biotechnology and in many other areas. The thesis treats methods for system identification and control of such nonlinear systems, and applies the proposed methods to a solar heating/cooling plant. READ MORE

7. 5. Control Strategies for Machining with Industrial Robots

   Author : Olof Sörnmo; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Robots; Machining; Control;

   Abstract : This thesis presents methods for improving machining with industrial robots using control, with focus on increasing positioning accuracy and controlling feed rate. The strong process forces arising during high-speed machining operations, combined with the limited stiffness of industrial robots, have hampered the usage of industrial robots in high-end machining tasks.
