  1. 11. Skibot 1.0, a Poling Cross-Country Skiing Robot

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Otto Kalliorinne; [2022]
    Nyckelord :Coordinate frame; Direction cosines; ZMP; GPS; DOF; SMC; Fuzzy logic; DC-motor; UART; I2C; Microcontroller;

    Sammanfattning : This thesis project covers the development of a cross country skiing robot, with the purpose of being used as an instrument for measuring gliding properties of skis. The robot used in total 4 servomotors to control the motion of right and left arms with poles attached. LÄS MER

  3. 12. Pitcher : An automatic guitar tuner

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Hannes Andersson; John Sjöberg; [2021]
    Nyckelord :Arduino; mechatronics; autocorrelation; guitar tuner; pitch detection algorithm; Arduino; mekatronik; autokorrelation; gitarrstämmare; tonavläsning;

    Sammanfattning : Pitcher is a prototype which makes it easier for inexperienced guitar players to tune their guitars without any prior knowledge required. This thesis will explore how the construction varies between the usage of DC and a stepper motor, how reliable the tuner is and how long it takes to tune the guitar. LÄS MER

  4. 13. Automatic Torque Control for Bicycle Driven Brushless DC (BLDC) Generator

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Luke Müller; Kasper Sjöström; [2021]
    Nyckelord :BLDC; brushless dc generator; brushless dc motor; JFET; Torque; Generator Torque; Automatic Torque Control; Field Effect Transistor; PWM;

    Sammanfattning : This work was carried out on behalf of Science Safari. Science Safari wants to create a product that facilitates the understanding of how much physical work is required to create electrical energy. This is done by cranking the pedals of a bicycle. LÄS MER

  5. 14. Design, simulation and HIL testing of an electric propulsion system of an electric scooter with brushless DC motor using field-oriented control Digital Twin of an electric scooter

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Jatin Anand; [2021]
    Nyckelord :;

    Sammanfattning : A motor control algorithm to control a brushless DC motor has been implemented and tested in this master thesis. Model-based development approach has been applied to implement the entire system that includes the control algorithm (Field-Oriented Control) and the model of a brushless DC motor. LÄS MER

  7. 15. Optimizing a servo drive using Field Oriented Control

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Lukas Land; [2021]
    Nyckelord :antenna; servo; foc; pmsm; vector engine; field oriented control; electrical motor; servo; fältorienterad kontroll; elmotor;

    Sammanfattning : An optimization of a servo system for a satellite antenna system wasperformed. A brushless DC motor with an angle encoder was used, whoseangular velocity had to be controlled with great precision. Specializedhardware was used to implement field oriented control to directlycontrol the torque and magnetic flux of the motor. LÄS MER
