1. 11. Minimum-time sliding mode control of robot manipulators

   Författare :Boyko Iliev; Ivan Kalaykov; Krzysztof Kozlowski; Örebro universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; minimum-time sliding mode control; sliding mode control; maximum-slope sliding lines; Takagi-Sugeno fuzzy systems; robot manipulators; reglerteknik; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

   Sammanfattning : Robot manipulators have a complex and highly nonlinear dynamics, accompanied with a high degree of uncertainty. These properties make them difficult for time-optimal control. The theory of sliding mode control can provide methods, able to cope with the uncertainty and nonlinearity in the system. LÄS MER

3. 12. Control and Communication-Schedule Co-design For Networked Control Systems

   Författare :Masoud Bahraini; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Networked Control Systems; Robust Invariance; Communication Scheduling;

   Sammanfattning : In a networked control system (NCS), the control loop is closed through a communication medium. This means that sensor measurements and/or control signals can be exchanged through a communication link. LÄS MER

4. 13. 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

5. 14. Robust Water Balance Modeling with Uncertain Discharge and Precipitation Data : Computational Geometry as a New Tool

   Författare :José-Luis Guerrero; Sven Halldin; Stefan Uhlenbrook; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alpha shape; Convex hull; Depth function; Discharge; Hydrological models; Honduras; Model calibration; Parameter-value estimation; Precipitation; Rating curve; Robust; Robustness; Uncertainty estimation; Water resources.; Alfaform; avbördningskurva; djupfunktion; Honduras; hydrologiska modeller; konvext hölje; modellkalibrering; nederbörd; osäkerhetsskattning; parametervärdesskattning; robust; robusthet; vattenföring; vattenresurser; Hydrology; Hydrologi;

   Sammanfattning : Models are important tools for understanding the hydrological processes that govern water transport in the landscape and for prediction at times and places where no observations are available. The degree of trust placed on models, however, should not exceed the quality of the data they are fed with. LÄS MER

7. 15. Reinforcement Learning and Optimal Adaptive Control for Structured Dynamical Systems

   Författare :Damianos Tranos; Alexandre Proutiere; Pontus Giselsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reinforcement Learning; Adaptive Control; Dynamical Systems; Control Theory; Control Engineering; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : In this thesis, we study the related problems of reinforcement learning and optimal adaptive control, specialized to specific classes of stochastic and structured dynamical systems. By stochastic, we mean systems that are unknown to the decision maker and evolve according to some probabilistic law. LÄS MER
