1. 1. Distributed Control for Spatio-Temporally Constrained Systems

   Författare :Adrian Wiltz; Dimos V. Dimarogonas; Jonas Mårtensson; Matthias Müller; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distributed model predictive control; control barrier functions; spatio-temporal constraints; constrained control; multiagent systems; distribuerad modell prediktiv styrning; kontrollbarriärfunktion; tillstånds-temporala begränsningar; begränsade system; multiagentsystem;

   Sammanfattning : In this thesis, we develop methods leading towards the distributed control of spatio-temporally constrained systems. Overall, we focus on two different approaches: a model predictive control approach and an approach based on ensuring set-invariance via control barrier functions. LÄS MER

3. 2. Draw control strategy for sublevel caving mines : A holistic approach

   Författare :Gurmeet Shekhar; Håkan Schunnesson; Anna Gustafson; Jesper Martinsson; Laeeque Daneshmend; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Draw control strategy; sublevel caving SLC ; loading process; draw point; caving operation; Bayesian statistics; probability models; economic models; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Sammanfattning : Sublevel caving is an underground mass mining method used for extracting different types of ores from the earth crust. Mines using sublevel caving (SLC) as the primary mining method are generally highly mechanized with standardized and independent unit operations. LÄS MER

4. 3. Approximate Solution Methods to Optimal Control Problems via Dynamic Programming Models

   Författare :Yuchao Li; Jonas Mårtensson; Karl H. Johansson; Pontus Giselsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal control; dynamic programming; model predictive control; Electrical Engineering; Elektro- och systemteknik; Optimization and Systems Theory; Optimeringslära och systemteori;

   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, this thesis introduces some suboptimal schemes via abstract dynamic programming models.

7. 5. On Robotic Work-Space Sensing and Control

   Författare :Magnus Linderoth; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; computer vision; color constancy; motion blur; filter initialization; visual tracking; on-line trajectory generation; ball-catching robot; force control; robotic assembly; force estimation; perception-action capabilities.;

   Sammanfattning : Industrial robots are fast and accurate when working with known objects at precise locations in well-structured manufacturing environments, as done in the classical automation setting. In one sense, limited use of sensors leaves robots blind and numb, unaware of what is happening in their surroundings. LÄS MER
