Linearization and Nonlinear Control in flight-Controls and Aeroelasticity for Civil Aircraft Using MATRIXx

This Master Thesis has been written at EADS (European Aeronautic Defence and Space Company) Airbus in Bremen.The work contains a description of a few methods when linearising SystemBuild models in MATRIXx. MATRIXx is a tool for matrix manipulations (similar to Matlab) and SystemBuild is a graphical modeling environment (similar to SimuLink). The methods examined are the linearization command “lin”

Construction and Control of an Inverted Pendulum

The aim of this master thesis is to develop a laboratory process that Saab Ericsson Space AB (SE) can use to demonstrate their fault tolerant computer systems at exhibitions. The process is an inverted pendulum shaped as a rocket to symbolize that the company develops fault tolerant control systems for satellites and carrier rockets e.g. for Ariane 5. The inverted pendulum is a classical control

New Control Concept for Haldex Limited Slip Coupling

The aim of this master thesis is to investigate a new control principal for Haldex Limited Slip Coupling. HLSC can be characterized as a hydraulic slip coupling intended to be part of a 4WD-system for passenger vehicles fitted between the front and rear axle. The investigation is to be both theoretical and practical. The current system can be described with the three following functional blocks:

A Robot Playing Scrabble Using Visual Feedback

We have used a robot and a camera to design and implement a system which is able to play the known game Scrabble. To make this possible we have constructed a robot system and a vision system. The vision system task is to find the position of the cubes. The robot system uses these positions to generate the trajectories. The feedback from the camera is used to correct the trajectory. That the system

Nonlinear Modeling of Locomotive Propulsion System and Control

In this report the motor side of a converter driven AC-locomotive is studied and modeled. The motor side consists of an asynchronous electrical engine, an indirect self controller, a voltage converter, a Pulse Width Modulator(PWM) and the train mechanics. The converter is supplied with voltage from a DC-link. The link is connected to a line converter which transfers energy from the railway net to

Olovligt spridande av privata bilder på internet

Uppsatsen redogör för rättsläget kring olovligt spridande av privata bilder på internet. I dagsläget bedöms sådant spridande vanligtvis som förtal i Sverige. För att något ska utgöra förtal ska en uppgift ha spridits som varit ägnad att utsätta personen för andras missaktning. Bedömningen av huruvida en uppgift varit ägnad att utsätta en person för andras missaktning och huruvida personens ära bliThe subject of this essay is the legal situation regarding unauthorized distribution of private photos on the Internet. Today, such distribution is usually judged as defamation in Sweden. For something to constitute defamation, information shall have been spread that was intended to subject the person to other people's contempt. The determination of whether a statement was likely to expose a p

EU: Education Policies and Third Countries. Civilian Power or "Just" Foreign Policy?

Despite the lack of attention from academia, there are concrete examples that show an attempt to Europeanize the education policies and institutions of countries outside of the EU. This dissertation investigates the relationship between education and foreign policy, looking at the partnership between EU and third countries. Following a social constructivist theoretical framework, the results of th

Laglottsskyddet i moderna familjekonstellationer - Förskott på arv och det förstärkta laglottsskyddet

Denna uppsats ska utreda och diskutera ifall syftet med arvsrättens regler om förskott på arv och det förstärkta laglottsskyddet uppfylls för bröstarvingar i moderna familjekonstellationer. Gällande rätt avseende förskott på arv och det förstärkta laglottsskyddet har studerats. Dessa två institut reglerar gåvor som föräldrar, under sin livstid, givit till något barn och hur gåvorna ska hanteras vi

Koncernen och värdeöverföringen

Uppsatsen behandlar vissa frågor kopplade till värdeöverföringar i koncernmiljö. En koncern ses ofta, i alla fall ur ett ekonomiskt perspektiv, som en enhet men moderbolag och dotterbolag ses aktiebolagsrättsligt som skilda rättssubjekt med egen förmögenhet och egna borgenärer. Det som brukar kallas förtäckt värdeöverföring definieras i aktiebolagslagen (2005:551) som en ”annan affärshändelse somThis paper describes a few questions relating to value transfers within company groups. A company group is often seen as a whole, at least from an economic point of view. The parent company and its subsidiaries are, however, in Swedish company law seen as different entities with their own respective assets and creditors. A transaction described in the Swedish Companies Act (2005:551) as ”another
