21. Development of an experimental six-phase induction machine drive
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)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
22. Velocity and Steering Control for Automated Personal Mobility Vehicle
Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesignSammanfattning : 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.

23. Parameter extraction in lithium ion batteries using optimal experiments
Master-uppsats, KTH/FordonsdesignSammanfattning : 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
24. Energy Consumption Optimization of Electric Vehicles
Master-uppsats, KTH/FordonsdynamikSammanfattning : 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
25. Active and semi-active suspensions for articulated vehicles to minimise tyre wear
Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesignSammanfattning : 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
