1. 6. Performance Trade-offs for Ultra-Reliable Low-Latency Communication Systems

   Författare :Sebastian Schiessl; James Gross; Mikael Skoglund; Cenk Gursoy; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : In this dissertation, we consider wireless systems for ultra-reliable low-latency communication (URLLC). URLLC systems are required for example in industrial closed loop control systems, where data must be transmitted within a short target delay of at most a few milliseconds. LÄS MER

3. 7. Stochastic Invariance and Aperiodic Control for Uncertain Constrained Systems

   Författare :Yulong Gao; Karl H. Johansson; Alessandro Abate; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; controlled invariant set; stochastic system; constraint; uncertainty; reachable set; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Uncertainties and constraints are present in most control systems. For example, robot motion planning and building climate regulation can be modeled as uncertain constrained systems. In this thesis, we develop mathematical and computational tools to analyze and synthesize controllers for such systems. LÄS MER

4. 8. Probabilistic Calibration of Building Energy Models : For Scalable and Detailed Energy Performance Assessment of District-Heated Multifamily Buildings

   Författare :Lukas Lundström; Erik Dahlquist; Angela Sasic; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : There is a global need to reduce energy consumption and integrate a larger share of renewable energy production while meeting expectations for human well-being and economic growth. Buildings have a key role to play in this transition to more sustainable cities and communities. LÄS MER

5. 9. Machine Learning for Wireless Link Adaptation : Supervised and Reinforcement Learning Theory and Algorithms

   Författare :Vidit Saxena; Joakim Jaldén; Mats Bengtsson; Hugo Tullberg; Jakob Hoydis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Communications; Reinforcement Learning; Multi-Armed Bandits; Thompson Sampling; Convex Optimization; Deep Learning; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Wireless data communication is a complex phenomenon. Wireless links encounter random, time-varying, channel effects that are challenging to predict and compensate. Hence, to optimally utilize the channel, wireless links adapt the data transmission parameters in real time. LÄS MER

7. 10. On some continuous-time modeling and estimation problems for control and communication

   Författare :Yasir Irshad; Magnus Mossberg; Magnus Jansson; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Identification; Parameter Estimation; Continuous-time Stochastic Systems; Networked Control Systems; Errors-in-variables Systems; Wireless Channel Modeling; Closed-loop Identification; Physics; Fysik;

   Sammanfattning : The scope of the thesis is to estimate the parameters of continuous-time models used within control and communication from sampled data with high accuracy and in a computationally efficient way.In the thesis, continuous-time models of systems controlled in a networked environment, errors-in-variables systems, stochastic closed-loop systems, and wireless channels are considered.
