2. 1. 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.

4. 2. 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.

5. 3. Fundamental Limitations of Distributed Feedback Control in Large-Scale Networks

   Author : Emma Tegling; Henrik Sandberg; Ali Jadbabaie; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed control; Large-scale systems; networked control; decentralized control; fundamental limitations; networked systems; frequency control; smart grid; consensus; spatial invariance; power system dynamics; microgrids; vehicular formation systems; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Networked systems accomplish global behaviors through local feedback interactions. The purpose of a distributed control design is to select interaction rules and control protocols that achieve desired global control objectives. 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
