2. 1. Tools for Autonomous Process Control

   Author : Anders Wallén; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sequential control; software architectures; fast set point response; spectral estimation; frequency domain identification; relay feedback; non-linear system identification; Autonomous Control; Process Control; Grafcet; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : There is an ongoing trend towards higher automation level in process control systems. The purpose of a plant is to manufacture some product at a high production rate with a consistent quality, while minimizing the use of resources in terms of energy consumption, raw material and labor.

4. 2. Geometric Control of Thrust Propelled Systems

   Author : Pedro Miguel Ótão Pereira; Dimos V. Dimarogonas; Jana Tumova; Panagiotis Tsiotras; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear control; geometric control; thrust propelled systems; slung load transportation; aerial tethered transportation; control of aerial vehicles; tracking and stabilization; global stabilization; bounded control; disturbance removal; distributed control; attitude synchronization; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis was motivated and inspired by the AEROWORKS project, a European research project, whose main goal was to deploy multiple heterogeneous unmanned aerial vehicles in environments where human intervention is restricted.In particular, this thesis focuses on control of aerial vehicles for the purposes of cargo transportation, an application of interest, for example, in inspection and maintenance of aging infrastructures.

5. 3. Modeling and Control of the Paper Machine Drying Section

   Author : Ola Slätteke; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; Moisture control; Paper-making; Pressure control; Predictive Control; Mid-ranging Control; Wood; Drying Section Modeling; Automation; control engineering; robotics; pulp and paper technology; Pappers- och massateknik;

   Abstract : The topic of this thesis is modeling and control of the last part of the paper machine - the drying section. Paper is dried by letting it pass through a series of steam heated cylinders and the evaporation is thus powered by the latent heat of vaporization of the steam. READ MORE

6. 4. Extremum Seeking Control : Stability, Accuracy, and Applications

   Author : Khalid Atta; Ying Tan; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Abstract : In many applications, there is a variable that indicates the overall performance and that must be maximized, such as the output of a hydro power turbine or a mineral processing plant, or that must be minimized, such as CO2 emissions or the consumption of resources. Extremization of this variable (maximization or minimization) through adjusting the influencing manipulated variables is occasionally required without prior knowledge of the optimal values of the manipulated variables or of the optimized variable.

7. 5. Applications of Information Inequalities to Linear Systems : Adaptive Control and Security

   Author : Ingvar Ziemann; Henrik Sandberg; Alexandre Proutiere; Nikolai Matni; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stochastic Adaptive Control; Machine Learning; Fisher Information; Secure Control; Fundamental Limitations; Reinforcement Learning; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis considers the application of information inequalities, Cramér-Rao type bounds, based on Fisher information, to linear systems. These tools are used to study the trade-offs between learning and performance in two application areas: adaptive control and control systems security. READ MORE
