1. 21. Development of an experimental six-phase induction machine drive

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Adam Bianchi; [2021]
   Nyckelord :Asymmetrical six-phase induction machine; indirect rotor field oriented control; machine rewinding; multiphase electrical machines; PCB design; speed control; the star of the slot .; Asymmetrisk sexfasig asynkronmaskin; flerfasiga elektriska maskiner; hastighetsreglering; indirekt rotorfälts orienterad reglering; kretskorts design; maskinomlindning; the star of the slot .;

   Sammanfattning : Electrical machines with more than three phases are usually called multiphase electrical machines and they can have several advantages compared to conventional three-phase electrical machines such as a lower content of space-harmonics, lower torque ripple and better fault tolerance. This degree project involves rewinding of a three-phase induction machine into an asymmetrical six-phase machine. LÄS MER

3. 22. Velocity and Steering Control for Automated Personal Mobility Vehicle

   Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Författare :Kui Wang; [2021]
   Nyckelord :Model Predictive Control; Automated Personal Mobility Vehicle; Velocity; Steering; Modellprediktiv Reglering; Automatiserat Personligt Mobilitetsfordon; Hastighet; Styrning;

   Sammanfattning : In this thesis, a Model Predictive Control (MPC) based re-planning and control system is proposed. The MPC re-planner will generate a collision-free path for the controlled vehicle when obstacles are detected, and the controller will make the vehicle move along the reference or re-planned path by adjusting its velocity and steering angle.

4. 23. Parameter extraction in lithium ion batteries using optimal experiments

   Master-uppsats, KTH/Fordonsdesign

   Författare :Venu Gopal Prathimala; [2021]
   Nyckelord :Lithium-ion battery; State of Charge; Physics-based battery models; Model parameterization; Optimal experiments; Sensitivity analysis; Scanning electron microscopy; Brunauer–Emmett–Teller; Litiumjonbatteri; fysikbaserade batterimodeller; modellparameterisering; optimala experiment; känslighetsanalys; skanningelektronmikroskopi; Brunauer – Emmett – Teller; batteri elfordon;

   Sammanfattning : Lithium-ion (Li-Ion) batteries are widely used in various applications and are viable for automotive applications. The effective management of Li-Ion batteries in battery electric vehicles (BEV) plays a crucial role in performance and range. LÄS MER

5. 24. Energy Consumption Optimization of Electric Vehicles

   Master-uppsats, KTH/Fordonsdynamik

   Författare :Zhifeng Sun; [2021]
   Nyckelord :Electric vehicle; torque allocation; regenerative braking; LQR; rear axle steering; Elfordon; tilldelning av vridmoment; regenerativa bromsstrategier; LQR; bakaxelstyrning;

   Sammanfattning : This master thesis report has studied several methods to improve the energy consumption of an electric vehicle equipped with two permanent magnet synchronous motors. Two driving torque distribution maps are developed based on efficiency map and load transfer, respectively. The drive torque distribution map based on the efficiency map shows up to 8. LÄS MER

7. 25. Active and semi-active suspensions for articulated vehicles to minimise tyre wear

   Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Författare :Haoran Zhang; [2021]
   Nyckelord :Articulated vehicle; tyre wear; quarter car model; semi-active and active suspension; Ledat fordon; däckslitage; kvartsbilsmodell; semiaktiv och aktiv fjädring;

   Sammanfattning : Tyre wear is a vital problem in vehicles, especially in articulated vehicles because of their heavier axle loads. Tyre wear can not only do harm to vehicle dynamics but also cause tyre particle emissions. Therefore, solutions that can minimise tyre wear are where this thesis work focuses. LÄS MER
