  1. 1. Sensorless Field-Oriented Control and Position Estimation

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Roberts Bitenieks; Lars Brander; [2023]
    Keywords : Sensorless rotor position estimation; High-frequency injection; Technology and Engineering;

    Abstract : This master's thesis investigates the feasibility of implementing field-oriented control for a BLDC motor without relying on a position sensor from a standstill up to 400 rad/s. To achieve this objective, various approaches were used at standstill and high speeds. READ MORE

  3. 2. Performance metrics and velocity influence for point cloud registration in autonomous vehicles

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Óscar Poveda Ruiz; [2023]
    Keywords : autonomous vehicle; localization; registration; metrics; error; classification; estimation; autonomt fordon; lokalisering; registrering; mätvärden; fel; klassificering; uppskattning;

    Abstract : Autonomous vehicles are currently under study and one of the critical parts is the localization of the vehicle in the environment. Different localization methods have been studied over the years, such as the GPS sensor, commonly fused with other sensors such as the IMU. READ MORE

  4. 3. 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.

  5. 4. Wrist Angle Estimation Using Two Wearable Inertial Measurement Units

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Arvin Razavi; [2023]
    Keywords : IMU wrist angle estimation; Wrist absolute angle; IMU-based human motion capture; orientation filter; Complementary filter; Kalman filter; IMU handledsvinkeluppskattning; handleds absolutvinkel; IMU-baserad mänsklig rörelsefångst; orienteringsfilter; komplementfilter; Kalman-filter;

    Abstract : Hand-intensive work is closely related to the prevalence of upper body and hand/wrist work-related musculoskeletal disorders (WMSDs) in office work, manufacturing, service industries, as well as the healthcare industry. Some risk factors include vibrations, forceful exertions, heavy manual handling, repetitive motions, and prolonged nonneutral wrist postures. READ MORE

  6. 5. Evaluation of Geopositioning Using Frequency Responses From Radio Propagation Measurements

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

    Author : Jessica Ye; Johan Lesko; [2023]
    Keywords : ;

    Abstract : Satellite reliant navigation systems may struggle in urban environments as tall buildings mayobstruct necessary direct lines of sight with satellites. There have been multiple studiesexamining how WIFI fingerprinting may be used for indoor positioning. READ MORE
