  1. 1. Traffic State Estimation on Swedish Highways : Model Comparison using Multisource Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jiaqi Xu; [2023]
    Keywords : Traffic State Estimation; Macroscopic Traffic Model; Extended Kalman Filter; Particle Filter; Data Fusion; Trafiklägesuppskattning; Makroskopisk trafikmodell; Utökad Kalman-filter; Partikelfilter; Datafusion;

    Abstract : 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. READ MORE

  3. 2. Design and Implementation of a Rocket Launcher Hybrid Navigation

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Omar Ugolini; [2023]
    Keywords : launch vehicle navigation; delayed Kalman filter; strapdown; navigering av bärraketer; fördröjt Kalman-filter; strapdown;

    Abstract : 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.

  4. 3. A Digital Phase-Locked Loop for Frequency Synthesis using an Adaptive Pulse Shrinking TDC

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Viktor Lewin; [2023]
    Keywords : Phase-locked loop; PLL; DPLL; Frequency Synthesis; TDC; PFD; Technology and Engineering;

    Abstract : 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. READ MORE

  5. 4. Improving the guidance, navigation and control design of the KNATTE platform

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Lars Lundström; [2023]
    Keywords : Multisensor Data Fusion; Nonlinear Kalman Filter; Neural Network;

    Abstract : 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.

  6. 5. Embedded Control of a Rotary Inverted Pendulum

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Ankit Khandeparkar; [2023]
    Keywords : ;

    Abstract : 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++. READ MORE
