1. 1. Control of EGR and VGT for emission control and pumping work minimization in diesel engines

   Författare :Johan Wahlström; Lars Nielsen; Lars Eriksson; Tore Hägglund; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mean value modeling; Oxygen fuel ratio; EGR-fraction; System analysis; Sign reversal; PID-control; European Transient Cycle; Automatic control; Reglerteknik;

   Sammanfattning : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. LÄS MER

3. 2. Glycemic Control and Temperature Control in Buildings

   Författare :Meike Stemmann; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes; Prediction; Optimization; Decision Support System; Inverted Decoupling; PID; Buildings; Ventilation System;

   Sammanfattning : This thesis consists of two parts, applying concepts from automatic control to different application areas.The first part of this thesis concerns the development of an optimization-based algorithm, determining the size of insulin and glucose doses for patients suffering from Diabetes Mellitus and treated with multiple insulin injections.

4. 3. Modelling and Lagrangian control of mixed traffic: platoon coordination, congestion dissipation and state reconstruction

   Författare :Mladen Čičić; Karl Henrik Johansson; Miroslav Krstić; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic control; Lagrangian control; mixed traffic models; Intelligent Transportation Systems; Connected and Automated Vehicles; traffic congestion; platoon coordination; moving bottlenecks; bottleneck decongestion; stop-and-go wave dissipation; traffic state reconstruction; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Traffic congestion is a constantly growing problem, with a wide array of negative effects on the society, from wasted time and productivity to elevated air pollution and reduction of safety. The introduction of connected, autonomous vehicles enables a new, Lagrangian paradigm for sensing andcontrolling the traffic, by directly using connected vehicles inside the traffic flow, as opposed to the classical, Eulerian paradigm, which relies on stationary equipment on the road.

5. 4. Learning to Control the Cloud

   Författare :Albin Heimerson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Reinforcement Learning; Learning-Based Control; Microservices; Datacenter; Autoscaling; Load Balancing; Neural Networks;

   Sammanfattning : With the growth of the cloud industry in recent years, the energy consumption of the underlying infrastructure is a major concern.The need for energy efficient resource management and control in the cloud becomes increasingly important as one part of the solution, where the other is to reduce the energy consumption of the hardware itself.

7. 5. Modeling and Model-based Control of Automotive Air Paths

   Författare :Robin Holmbom; Lars Eriksson; Daniel Jung; Christopher Onder; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The strive towards cleaner and more efficient combustion engines, driven by legislation and cost, introduces new configurations, as exhaust gas recirculation, turbocharging, and variable valve timing, to name a few. Beside all the positive effects on the emissions and fuel consumption, they all affect the air-charge system, which increases the cross-couplings within the air-path control, making it an even more complex system to control.
