Missilstyrning med Model Predictive Control

This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.

Luftvärnets verkanssystem i Utlandstjänst

This paper aims to analyze if ground based air defence of the Swedish Defence Forces is sufficiently equipped to protect units serving abroad. The Swedish ground based airdefece has its roots in the era of the cold war but the focus of Swedish Defence Forces has shifted from defending Swedish territory to peace keeping and peace enforcement in foreign countries. First I will take a look at the base factors for ground based air defence units serving in a peace keeping or enforcing mission and then use this to define what abilities you would like to have in a ground based air defence system. Finally I will compare these abilities whit the abilities of the ground based air defence systems that are in use whit the Swedish Defence Forces.My conclusion is that the question can´t be answered on a generel level but every mission has to be analyzed individualy.The author of this paper is Cadet Tobias Jönsson studying at the The Armed Forces Technical School to become an officer in the Swedish Defence Forces..

Optimering av slutfasstyrning

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

Sveriges säkerhetspolitik under 2000-talet : En analys ur ett liberalt och ett realistiskt perspektiv

The purpose of this study was to examine and explain Sweden?s defence and security policy during the twenty-first century. The method that was used in this research was a case study. The material that was used were government documents focusing on this area of policy, and numerous books concerning the theoretical perspectives on international relations and defence security policy. The study is of an explaining art and the analysis explains Sweden?s security and defence policy during the twenty-first century. The analysis explains this by testing it against a liberal and a realist view on international relations. The conclusion of the study is that Sweden?s defence and security policy has been liberal during this time period ? and still is.

Kinetikens tecken: en experimentell studie i samspelet mellan kroppens rörelser och dess försvarsmekanismer

Relationships between defence mechanisms and body movements were investigated in regard to three hypothesis; I. that a difference in frequency of body movements correlates to different signs of defence mechanisms, II. that themes of body movements can be identified in regard to signs of defence mechanisms, III. that no significant differences will be found between the different groups of gender. The aim of the study was to seek a relation between quasicommunicative body movements and defence mechanisms.

Feministiskt självförsvar - för eller emot?

The aim of this thesis is to discuss and analyse the media debate about feminist self-defence, by pointing out the pros and the cons. The arguments in favour could be separated into three different parts: statistical arguments, psychological arguments and justice arguments. The counter arguments could also be separated into three parts: general arguments, violence-related arguments and gender-related arguments. In short, feminist self-defence is built on women's experiences of men's violence. It contains three different parts to help women avoid violence, threat of violence, insult and sexual harassment.

MISSILE : Utvecklingsmodell och strategier för framgångsrika publika webbtjänster

Att utveckla en publik webbtjänst kan tyckas lätt, men att få denna till en framgångsrik och lönsam applikation är en annan sak. Konkurrensen är idag stenhård och en bra applikation är långt ifrån det enda man behöver för att lyckas.Studiens syfte var att kartlägga och öka förståelsen kring publik webbtjänstutveckling, ett område som tidigare inte fått så stor uppmärksamhet i den akademiska världen. Studien bygger på ett empiriskt material insamlat genom intervjuer med några av Sveriges främsta IT-entreprenörer inom området. Studien inkluderade även ett praktiskt moment där utveckling av inbjudningssajten InviClub.se genomförts för att praktiskt testa teorierna.Vår studie visade på att traditionella systemutvecklingsmetoder är svåra att tillämpa på detta område. En faktor som visade sig vara av yttersta vikt för lyckade projekt var snabbhet, något som de traditionella modellerna RUP och Vattenfallsmodellen inte prioriterar.

Kubakrisen : En tidningsstudie om svenska morgontidningars rapportering kring krisen

AbstractKubakrisen; En tidningsstudie om svenska morgontidningars rapportering kring krisen The Cuban Missile Crisis; A media study of Swedish morning papers reporting about the crisis The purpose of the survey is to illustrate how four Swedish newspapers, Svenska Dagbladet, Göteborgs Handels- och Sjöfartstidning, Dagen and Ny Dag reports about the Cuban missile crisis based on the questions. The survey highlights what distinguishes the morning papers and by how they take the position of the ship blockade against Cuba that United States issued and what position they take on who to blame in the conflict, but also how leaders Khrushchev, Kennedy and Castro portrayed. The study is based on the basis of a newspaper study and theory of priming serves as an instrument for the collection of materials. The survey results show in the first issue of how the papers stand to US ship blockade, which SvD endorses, while GHT and Ny Dag condemns it and Dagen stand in the middle without any real position. Previous studies treated SvD stance during the Cold War, shows that during the Vietnam War in 1965 SvD was very critical of the USA and their involvement. In this study, regarding the Cuban missile crisis, SvD are most clearly pro-US while Ny Dag accuse and highlights strong criticism of the United States. As for Chrusjtjov, Kennedy and Castro, the survey shows that three out of four newspapers writes about a surprised Chrusjtjov, who had gone too far and a Kennedy who are determined and implacable.

Nordiskt försvarssamarbete i åtstramningens tidevarv : En studie av förutsättningar för det norsk-svenska försvarssamarbetet

This study uses European researcher Tomas Valasek?s hypothesis about factors required for defence cooperation in order to achieve conditions which can be successfully applied to the Nordic defence cooperation NORDEFCO. The study uses only Norway and Sweden on the grounds that they are the original actors and the driving forces behind the defence cooperation. The factors studied are; the countries' strategic culture, solidarity and trust between countries, similarity in military forces, if similar conditions prevail in the defence industry and if the intentions of cooperation have been clarified.Mainly government documents in the form of propositions, orientations and defence documents are studied, together with previous research in this area and, especially, interviews with representatives of NORDEFCO at military level and policy level as well as outside perspectives from the military attachés in each country. With the intention of studying the extent to which the factors Valasek features may prove to be significant in assessing the conditions for enhanced cooperation in NORDEFCO, the study raises the question of how it is possible to find expressions for the factors.

Ryssland och missilförsvaret. En extern/intern analys av Rysslands negativa inställning till USA:s planerade missilförsvar i Polen och Tjeckien

Våren 2007 offentliggjorde USA planerna på att upprätta ett missilförsvar i Polen och Tjeckien som ett skydd mot missilangrepp från Iran. Från Ryssland blev reaktionen mot planerna kraftfull. Retoriken från Moskva påminde om kalla krigets dagar. Vilka är de bakomliggande orsakerna till denna starka reaktion? Syftet med studien är att undersöka vilka orsaker, såväl externa som interna, det är som styr den ryska inställningen.

Sverige och Nato : En studie om de svenska relationerna till Nato efter det kalla krigets slut

The purpose of this essay is to examine the Swedish relations to Nato and by doing so see on what terms the cooperation is executed and why. However, Sweden is not a member of Nato and is thereby not seen as an ally of the organization but even so Sweden has a close cooperation with Nato. The theories used in this essay is The Rational Actor Model and The Organizational Behaviour Model by Graham Allison and Philip Zelikow. To this a number of additional theorises are used as to complement these two main theories. The aim with these theories is to see which one gives the most satisfying explanation of the Swedish strategy to cooperate with Nato and still not be a member of the alliance or if all theorises are needed.

Oförsvarbart : argumentationen i media rörande Försvarsmaktens avveckling av överskott 2000-2003

The Swedish Military Defence is about to make a large reorganization. Surplus, everything from tanks to personal underwear, enough to equip 800,000 soldiers will be destroyed or sold to the highest bidder. This thesis is a discourse analysis about the argumentation in media between the Military and the enthusiast, who are interested in military vehicles and military surplus..

Kommunikation och Prestation : Aspekter på förhållandet mellan teamkommunikations innehåll, frekvens och problem, och teamresultat, studerat i en militär flygsimulator för grupper

A study of communication content, frequency and problems was performed at the Swedish Air Force Air Combat Simulation Centre, FLSC. The purpose was to investigate the connection between team communication and performance variables, to study communication problems during air combat and to employ and develop the PILOT method of communication problem analysis. Ten fighter pilots and four fighter controllers engaged in simulated air combat beyond visual range in teams on two sides, Blue and Red, with four pilots and one fighter controller each. Eight such training runs lasting 15 to 25 minutes were analyzed with regard to the Blue team?s communication during launch situations, i.e.

Försvarsenhetens arkiv : Examensarbete på länsstyrelsen i Södermanlands län

The defence unit´s archive stretches over a time limit between the middle of 1971 to the end of 1987. The records the archive mainly contains are concerning the civil defence, inspection and construction of shelters, war- and crisis planning. The majority of the records are registered record, as often is the case with an authority?s archives. The main problems that occurred concerned what should or shouldn´t be public, the principle of provenance and what to prioritize; finish the project before deadline or make sure the records are prepared for a storage that ideally should last for several lifetimes..

Nordiskt försvarssamarbete : Är det en ny företeelse eller en fortsättning på det som tidigare ägt rum i hemlighet?

There are changes in Sweden's foreign policy, and Sweden is no longer a non-aligned and neutral nation. Sweden has expressed a willingness to actively participate in creating peace and stability in the world by giving and receiving military assistance in case of war, crisis or disaster. This is described as complete turnaround in Swedish policy compared to the neutrality and non-alignment during the Cold war.However new research shows that defence cooperation is not new in the Nordic region. Sweden cooperated secretly with Denmark and Norway, two NATO countries, about co-operative defence of Scandinavia during the Cold War.Is our historical picture wrong and what we perceive as new and revolutionized not particularly new? Is today's open Nordic defence cooperation a continuation of what was done in secret during the Cold War? The essay investigates and compares two different Swedish defence cooperation?s where one was previously secret and the other is open.
