  1. 1. Online Minimum Jerk Velocity Trajectory Generation : for Underwater Drones

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Jakob Andrén; [2023]
    Nyckelord :reference generation; minimum jerk; rov; underwater drones; trajectory;

    Sammanfattning : This thesis studies real-time reference ramping of human input for remotely operated vehicles and its effect on system control, power usage, and user experience. The implementation, testing, and evaluation were done on the remotely operated Blueye Pioneer underwater drone. LÄS MER

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

    Författare :Xingyu Zhao; [2023]
    Nyckelord :keywords here: Deadbeat Predictive Current Control; Permanent Magnet Synchronous Motor; Flux Linkage Nonlinearity; Parameter Inaccuracies; Nonlinear Feedforward Compensation; Delayed Integral Action.; Deadbeat-prediktiv strömreglerin; Permanenta magnet-synkronmotorn; Ickelinjäriteter i flödeslänkningen; Felaktigheter i parametrar; Icke-linjär framåtmatningskompensation; Fördröjd integralåtgärd.;

    Sammanfattning : The Permanent Magnet Synchronous Motor (PMSM, also known as the servo motor) is a crucial component within robotic servo systems. To optimally respond to the torque demands sent from the high-level motion controller, the PMSM current controller must track the reference with speed and precision. LÄS MER

  4. 3. Predictive Control for Mitigating Solar Power Variations in Isolated Steam Power Systems

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Rasmus Björk; [2023]
    Nyckelord :;

    Sammanfattning : The need to reduce the amount of fossil fuel consumed by industry is vital. However, it is crucial to understand that industry is less inclined to shift its consumption from fossil fuels to renewable energy sources solely based on environmentalconcerns; to realistically make industry switch from fossil fuels to renewable energy sources, renewable energy sources must provide efficient results for industry.

  5. 4. Iterative Evaluation and Control Methods for Disturbance Suppression on a High Precision Motion Servo

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Claes Thunberg; Klara Kastensson; [2023]
    Nyckelord :Iterative feedback tuning; Iterative learning control; high precision motion control; Iterative methods for disturbance supression;

    Sammanfattning : Moore’s law states that the number of transistors in an Integrated Circuit (IC) doubles every two years. Ever-increasing performance in mask writing machinery is therefore required being the first step in the manufacturing process. Many factors affect the quality of the end product, with the motion control system playing an important role. LÄS MER

  7. 5. Predictive Deceleration Control

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

    Författare :Felix Collin; [2022]
    Nyckelord :Predictive control; Map information; Feedforward control; Deceleration control; Prediktiv reglering; Information från kartor; Framkopplingsreglering; Retardationsreglering;

    Sammanfattning : For vehicles equipped with electric motors there exist a possibility to recuperate energy during deceleration. This master’s thesis presents a driver support function, a Predictive Deceleration Control (PDC), that warns the driver when to release the accelerator pedal. LÄS MER
