2. 1. 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

4. 2. Statistical Learning, Dynamics and Control : Fast Rates and Fundamental Limits for Square Loss

   Author : Ingvar Ziemann; Henrik Sandberg; Raginsky Maxim; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Learning; Control Theory; Statistical Learning; Fundamental Limits; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Learning algorithms play an ever increasing role in modern engineering solutions. However, despite many recent successes, their performance in the context of dynamical and control systems is not exactly well-understood. READ MORE

5. 3. 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.

6. 4. Active control of vibration and analysis of dynamic properties concerning machine tools

   Author : Henrik Åkesson; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Control; Modal Analysis; Analog Controller;

   Abstract : Vibration in internal turning is a problem in the manufacturing industry. Vibrations appear under the excitation applied by the material deformation process during the machining of a workpiece. READ MORE

7. 5. A flexible real-time solution to modular design of an adaptive control system for turning

   Author : Thomas Lundholm; Bo Lindström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turning; adaptive control; real-time control; Manufacturing engineering; Produktionsteknik;

   Abstract : This thesis deals with the organization of an adaptive control system for turning and, furthermore, the development of an integration framework for subsystems in the adaptive control system. The thesis is organized in three main parts. READ MORE
