1. 11. Applications of Information Inequalities to Linear Systems : Adaptive Control and Security

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

   Sammanfattning : 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. LÄS MER

3. 12. Externally positive systems : Analysis and control based on combinatorial polynomials

   Författare :Liam Hamed Taghavian; Mikael Johansson; Cristian R. Rojas; Fabio Pasqualetti; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear systems; External positivity; Optimization; Non-overshooting control; Combinatorics; Complete monotonicity; Majorization.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Monotonic tracking is required in many control systems, including those that cannot tolerate any overshoots and undershoots in their closed-loop responses. Classical examples are found in vehicle cruise control and liquid tank level control. LÄS MER

4. 13. The Core of Aerial Robotic Workers : Generalized Modeling, Estimation, and Control

   Författare :Emil Fresk; George Nikolakopoulos; Thomas Gustafsson; Ming Cao; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerial robotics; generalized modeling; generalized estimation; generalized control; Reglerteknik; Control Engineering;

   Sammanfattning : In this thesis we are going to explore what the operational core, both mathematically and algorithmically, of an Aerial Robotic Worker consists of, in order to estimate its egomotion and parameters, and adaptively control the aerial vehicle. Moreover, the aim of this thesis is to be a condensed reference for the corresponding areas of aerial robotics, in order to provide a stable and complete foundation on which one can continue research on.

5. 14. Modelling and Control Methods with Applications to Mechanical Waves

   Författare :Hans Norlander; Bengt Carlsson; Torsten Söderström; Jonas Sjöberg; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; pole placement; linearization; vibration control; distributed parameter systems; wave propagation; Automatic Control; Reglerteknik;

   Sammanfattning : Models, modelling and control design play important parts in automatic control. The contributions in this thesis concern topics in all three of these concepts.The poles are of fundamental importance when analyzing the behaviour of a system, and pole placement is an intuitive and natural approach for control design.

7. 15. Quality-Driven Synthesis and Optimization of Embedded Control Systems

   Författare :Soheil Samii; Petru Eles; Zebo Peng; Samarjit Chakraborty; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Embedded control; distributed embedded systems; distributed control; control quality; control performance; scheduling; optimization; adaptive system; multi-mode system; fault tolerance; self-triggered control; Computer science; Datavetenskap;

   Sammanfattning : This thesis addresses several synthesis and optimization issues for embedded control systems. Examples of such systems are automotive and avionics systems in which physical processes are controlled by embedded computers through sensor and actuator interfaces. LÄS MER
