  1. 1. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

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

    Author : Simon Weideskog; [2024]
    Keywords : FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Abstract : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. READ MORE

  3. 2. Evaluation of Traction Control Systems for an Electric Forklift Truck

    University essay from Linköpings universitet/Fordonssystem

    Author : Mattias Karlsson; Sebastian Johansson; [2021]
    Keywords : forklift; traction control; maximum transmissible torque; model following control; sliding mode control; slip; asr; tcs; mfc; mtte; smc; electric vehicle; master thesis;

    Abstract : This thesis evaluates different controllers for traction control on an electric forklift truck and has been done in cooperation with Toyota Material Handling Manufacturing Sweden. The need for a traction control system has increased with the introduction of lithium-ion batteries replacing the older lead-acid batteries, reducing the battery weight and therefore the downward force on the driving wheel increasing the risk for slip.

  4. 3. Steering Control During μ-split Braking for an Autonomous Heavy Road Vehicle

    University essay from Linköpings universitet/Fordonssystem

    Author : Sebastian Haglund; Henrik Johansson; [2020]
    Keywords : steering; braking; autonomous; μ-split; split-μ; truck; vehicle; control;

    Abstract : A critical maneuver for a heavy vehicle is braking with different friction on the left and right hand side of the vehicle, called μ-split. This results in an unwanted yaw torque acting on the vehicle. During this situation, the driver maintains the lateral stability and follows the desired path by corrective steering. READ MORE

  5. 4. Improving Traction Efficiency in Off-Road Vehicles - A Sliding Mode Approach

    University essay from KTH/Optimeringslära och systemteori

    Author : Payam Maroufi; [2018]
    Keywords : Slip efficiency; sliding mode controller; sliding mode observer; articulated vehicles; wheel loader dynamic.; Slipeffektivitet; sliding mode regulator; sliding mode observerare; ledat fordon; hjullastarens dynamik.;

    Abstract : This report evaluates the option of using an equal slip controller, an effective rolling radius and rolling resistance force observer in a 4WD wheel loader. The vehicle studied is an under development- vehicle designed by Volvo CE. READ MORE

  6. 5. Velocity estimation in land vehicle applications - Sensor Fusion using GPS, IMU and Output-shaft

    University essay from KTH/Optimeringslära och systemteori

    Author : Christian Jonsson; [2016]
    Keywords : ;

    Abstract : In this project an alternative velocity-signal for Scania’s heavy-duty vehicles was investigated. The current velocity estimation is based on wheel-encoders obtained from other control-units like ABS- and EBSsystems. Furthermore the wheel-encoders may have poor properties at both high and low velocites. READ MORE
