1. 1. Development and evaluation of methods for control and modelling of multiple-input multiple-output systems

   Författare :Fredrik Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Input-output scaling; Modeling; Fiber length; Tensile Index; Hold-input; Decentralized control; Gramian based measures; Delays; LQG control; TMP; Uncertain data sets; Unreliable communication links; MIMO systems; Control configuration selection; Linear regression; Freeness; Shives; CTMP;

   Sammanfattning : In control, a common type of system is the multiple-input multiple-output (MIMO) system, where the same input may affect multiple outputs, or conversely, the same output is affected by multiple inputs. In this thesis two methods for controlling MIMO systems are examined, namely linear quadratic Gaussian (LQG) control and decentralized control, and some of the difficulties associated with them.

3. 2. Task-oriented control and coordination of multi-agent systems under varying constraints

   Författare :Pian Yu; Dimos V. Dimarogonas; Carlo Fischione; Christos Cassandras; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-agent systems; uncertain systems; temporal logics; event-triggered control; control synthesis; conflict resolution; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Multi-agent systems (MAS) offer a tremendous potential to improve the quality of modern society life. For instance, robot networks have been widely used for providing services such as search and rescue missions, surveillance and data collection, healthcare and entertainment. LÄS MER

4. 3. Uncertain demand prediction for guaranteed automated vehicle fleet performance

   Författare :Sten Elling Tingstad Jacobsen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility-on-Demand; Travel Demand Uncertainty; Energy Efficiency; Chance Constraint Optimization; Gaussian Process Regression; Stochastic Model Predictive Control; Fleet Opti- mization;

   Sammanfattning : Mobility-on-demand (MoD) services offer a convenient and efficient transportation option, using technology to replace traditional modes. However, the flexibility of MoD services also presents challenges in controlling the system. One of the major issues is supply-demand imbalance, caused by uneven stochastic travel demand. LÄS MER

5. 4. Predictive Techniques and Methods for Decision Support in Situations with Poor Data Quality

   Författare :Rikard König; Högskolan i Skövde; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Rule Extraction; Genetic Programming; Uncertainty estimation; Machine Learning; Artificial Neural Networks; Data Mining; Information Fusion; Information technology; Informationsteknik; Teknik; Technology;

   Sammanfattning : Today, decision support systems based on predictive modeling are becoming more common, since organizations often collect more data than decision makers can handle manually. Predictive models are used to find potentially valuable patterns in the data, or to predict the outcome of some event. LÄS MER

7. 5. 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
