1. 21. Approximate Methods of Optimal Control via Dynamic Programming Models

   Författare :Yuchao Li; Jonas Mårtensson; Karl H. Johansson; Moritz Diehl; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Dynamic Programming; Rollout; Model Predictive Control; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Optimal control theory has a long history and broad applications. Motivated by the goal of obtaining insights through unification and taking advantage of the abundant capability to generate data and perform online simulation, this thesis studies the discrete-time infinite horizon optimal control problems and introduces some approximate solution methods via abstract dynamic programming (DP) models.

   Sammanfattning : Cloud Computing, with its globally-accessible nature and virtually unlimited scalability, has revolutionized our daily lives since its widespread adoption in the early 2000s. It allows us to access our documents anywhere, keep in touch with friends, back up photos, and even remotely control our appliances. LÄS MER

7. 25. Complexity-aware Decision-making with Applications to Large-scale and Human-in-the-loop Systems

   Författare :Elis Stefansson; Karl H. Johansson; Henrik Sandberg; Iman Shames; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complexity-aware Decision-making; Automata Theory; Automatic Control; Optimal Control; Kolmogorov Complexity; Hierarchical Finite State Machines; Large-scale Systems; Human-in-the-loop; Game Theory; Human Decision-making; Autonomous vehicles; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : This thesis considers control systems governed by autonomous decision-makers and humans. We formalise and compute low-complex control policies with applications to large-scale systems, and propose human interaction models for controllers to compute interaction-aware decisions. LÄS MER
