1. Traffic State Estimation on Swedish Highways : Model Comparison using Multisource Data
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Due to the escalating demand for traffic information and management, the significance of traffic state estimation, which involves the assessment of traffic conditions on road segments with limited measurement data, is increasing. Two primary estimation methods are model-driven and data-driven. LÄS MER
2. Design and Implementation of a Rocket Launcher Hybrid Navigation
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Rocket Factory Augsburg (RFA) a German New Space Startup is developing a three-stage rocket launcher aiming at LEO/SSO orbits. A fundamental responsibility of the GNC team is the development of the rocket navigation algorithm to estimate the attitude, position, and velocity allowing the guidance and control loops to autonomously steer the rocket.

3. A Digital Phase-Locked Loop for Frequency Synthesis using an Adaptive Pulse Shrinking TDC
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : This thesis investigates a new type of Phase-Locked Loop (PLL) architecture which combines a phase/frequency detector (PFD) and a digital loop filter. The quantization is done by a time-to-digital converter which continuously shrinks the pulse coming from the PFD and registers how far it propagates. LÄS MER
4. Improving the guidance, navigation and control design of the KNATTE platform
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : For complex satellite missions that rely on agile and high-precision manoeuvres, the low-friction aspect of the space environment is a critical component in understanding the attitude control dynamics of the spacecraft. The Kinesthetic Node and Autonomous Table-Top Emulator (KNATTE) is a three-degree-of-freedom frictionless vehicle that serves as the foundation of a multipurpose platform for real-time spacecraft hardware-in-the-loop experiments, and allows emulation of these conditions in two dimensions with the purpose of validating various guidance, navigation, and control algorithms.

5. Embedded Control of a Rotary Inverted Pendulum
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : In modern-day contemporary control systems, such as robots, drones, and autonomous vehicles the control algorithms are bound to be implemented on embedded devices that pose a set of challenges and limitations such as low computational capacity and memory. Thus, it is crucial to design and implement efficient control algorithms while using low-level programming languages such as C / C++. LÄS MER
