1. 1. On Structure Exploiting Numerical Algorithms for Model Predictive Control

   Författare :Isak Nielsen; Daniel Axehill; Anders Hansson; Pontus Giselsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : One of the most common advanced control strategies used in industry today is Model Predictive Control (MPC), and some reasons for its success are that it can handle multivariable systems and constraints on states and control inputs in a structured way. At each time-step in the MPC control loop the control input is computed by solving a constrained finite-time optimal control (CFTOC) problem on-line. LÄS MER

3. 2. Structure-Exploiting Numerical Algorithms for Optimal Control

   Författare :Isak Nielsen; Daniel Axehill; Anders Hansson; Eric Kerrigan; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical Optimal Control; Model Predictive Control; Riccati Recursion; Parallel Algorithms; Low-Rank Modifications; Parametric Programming; Optimization; Explicit MPC; Moving Horizon Estimation; Partial Condensing;

   Sammanfattning : Numerical algorithms for efficiently solving optimal control problems are important for commonly used advanced control strategies, such as model predictive control (MPC), but can also be useful for advanced estimation techniques, such as moving horizon estimation (MHE). In MPC, the control input is computed by solving a constrained finite-time optimal control (CFTOC) problem on-line, and in MHE the estimated states are obtained by solving an optimization problem that often can be formulated as a CFTOC problem.

4. 3. Kommunindelning och demokrati : Om sammanläggning och delning av kommuner i Sverige

   Författare :Peder Nielsen; Anders Westholm; Barry Holmström; Lawrence E. Rose; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political science; territorial division; democracy; demos; community spirit; legitimacy; participation; municipality; local government; amalgamation; secession; municipality partition; Statsvetenskap; Political science; Statsvetenskap;

   Sammanfattning : This thesis focuses on the territorial dimension of democracy by studying the division of Swedish municipalities. It consists of two parts focusing on two types of changes to the division of municipalities: amalgamation and secession.The consequences of a series of amalgamation reforms are the starting point for the first part.

5. 4. Efficient Simulation and Optimal Control for Vehicle Propulsion

   Författare :Anders Fröberg; Lars Nielsen; Karl-Henrik Johansson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

   Sammanfattning : Efficient drive cycle simulation of longitudinal vehicle propulsion models is an important aid for design and analysis of power trains. Tools on the market today mainly use two different methods for such simulations, forward dynamic or quasi-static inverse simulation. LÄS MER

7. 5. Capacitance transient measurements on point defects in silicon and silicol carbide

   Författare :Hanne Kortegaard Nielsen; Anders Hallén; F. Damie Auret; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik; Electronics; Elektronik;

   Sammanfattning : Electrically active point defects in semiconductor materials are important because they strongly affect material properties like effective doping concentration and charge carrier lifetimes. This thesis presents results on point defects introduced by ion implantation in silicon and silicon carbide. LÄS MER
