1. Konceptframtagning av tether-spännare : Framtagning av koncept för spänningsanordning på en vinsch för offshore bruk
M1-uppsats, Linköpings universitet/ProduktrealiseringSammanfattning : When working under water at great depths, or in tough environments, remotely controlled underwater vehicles, so called ROV:s, are a good tool too use. With the help of these robots it is possible to work for longer periods of time and at larger depths then with ordinary divers. LÄS MER
2. Underwater Rao-Blackwellized Particle Filter SLAM using Stochastic Variational Gaussian Processes maps
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In this thesis, we introduce a Rao-Blackwellized Particle Filter (RBPF) for the algorithm Simultaneously Localizing and Mapping (SLAM) to be used on an Autonomous Underwater Vehicle (AUV) with a Stochastic Variational Gaussian Process (SVGP) algorithm. With a positive result, the combination was proven to be working. LÄS MER
3. Optimal Control Model for an Autonomous Underwater Vehicle
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The main goal with this thesis was to develop an optimal control model for anautonomous underwater vehicle (AUV) and evaluate whether reference trackingusing Model Predictive Control (MPC) based on a linear dynamics modeldescribing all six degrees of freedom (DOF) is a suitable method for waypointnavigation. MPC is an advanced receding horizon optimal control method capableof including constraints in the optimization. LÄS MER
4. Finding the most suitable auxiliary sonar for terrain-aided navigation and behavior-fusion based obstacle avoidance for an autonomous underwater vehicle
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Autonomous underwater vehicles are rapidly becoming more common and developed for both military as well as civilian applications such as; mine countermeasures or in the field of geoscience. One of the main issues these vehicles are facing today is the navigation capability. LÄS MER
5. Pulsfördelningsnätverk i störande miljö
Kandidat-uppsats, Linköpings universitet/Elektroniska Kretsar och SystemSammanfattning : Detta arbete har utförts i samarbete med Saab Seaeye och rör deras undervattensfarkost Sabertooth. En lokal GPS (global positioning system) genererar en PPS-signal (pulse per second) som används till att synkronisera klockor runtom i farkosten. Om denna signal har för hög överlagrad störning så kommer inte enheter fungera önskvärt. LÄS MER
