  1. 1. Design Optimization of Savonius Wind Turbine using CFD Simulations

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Vatsalkumar Manavar; [2023]
    Nyckelord :Savonius wind turbine; Computational fluid dynamics; Vertical axis wind turbine; Overlap ratio; Distance between blades; Power coefficient;

    Sammanfattning : This thesis is based on a simulation of the Savonius wind turbine. The Savoniusturbine is a simple vertical axis device, which has half cylindrical blades attached to the main shaft opposite to each other which creates the drag force from incoming wind and generates mechanical torque which drives the generator for electricity generation.

  4. 3. Torque-Based Load Estimation for Passenger Vehicles

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Tobias Nyberg; [2021]
    Nyckelord :Load Estimation; RLS; Recursive least squares; torque; torque-based; mass estimation; mass; passenger vehicle; estimation algorithm; load estimation algorithm; forgetting factor; RLS with forgetting factor;

    Sammanfattning : An accurate estimate of the mass of a passenger vehicle is important for several safety systems and environmental aspects. In this thesis, an algorithm for estimating the mass of a passenger vehicle using the recursive least squares methodis presented. LÄS MER

  5. 4. PiChess : Voice Controlled Robotic Chess Player

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Oscar De Brito Lingman; Axel Sernelin; [2021]
    Nyckelord :Mechatronics; Raspberry Pi; Chess; SCARA; Dynamixel; Mekatronik; Raspberry Pi; Schack; SCARA; Dynamixel;

    Sammanfattning : The purpose of this bachelor’s thesis was to create a robot that could play chess through voice recognition and robotics. The two areas to be investigated were the robot’s precision and speed. The reason for building a robot arm of the SCARA type was that it can easily pick up and place pieces with reach over the entire chessboard. LÄS MER

  7. 5. Optimal torque split strategy for BEV powertrain considering thermal effects

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

    Författare :Dhananjay Yadav; [2021]
    Nyckelord :Optimal torque-split control strategy; battery electric vehicles; thermal model of electric machines; system identification; model order reduction; co-simulation.; Optimal vridmomentsdelningsstyrningsstrategi; batteridrivna fordon; termiska modeller av elektriska maskiner; systemidentifiering; minskning av modellorder; samsimulering.;

    Sammanfattning : A common architecture for electric vehicles is to have two electric machines one each on the front and rear axle. Despite the redundancy, this configuration ensures performance. Being energy efficient is equally important for electric vehicles to deliver a sufficiently high range. LÄS MER
