  1. 1. Hanging Load Mock-Up For Experimental Setup To Test Flight System Stability

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Anthony Gundstedt; [2023]
    Nyckelord :drone; hanging; variable length; mixer matrix; PID; controller; microcontroller; RC; Telnet; I2C; FrSKY; Sbus; S.bus; Forestry; AirForestry; Swing; anti-swing; IMU; filter;

    Sammanfattning : Can we reduce disturbance, swing, and errors by delegating some of the tasks to a subsystem on the tool hanging from a drone to gain precision and dependability? This project covers developing and implementing a user-controlled prototype with an automatic control system and gripper for functionality and controlled movement in 5 DOF. AirForestry is developing a new way of working in the forestry business to provide a greener and healthier solution for the soil and the environment. LÄS MER

  3. 2. Centralized motion control of gas-hydraulic suspension on e-bus

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Robin Rutström Kugel; [2022]
    Nyckelord :;

    Sammanfattning : Most modern heavy vehicles use pneumatic suspension systems to adjust the height and stiffness of thesuspension by inflating or deflating air bellows with compressed air. The pneumatic suspension system hasbeen advantageous to use, even though the required components are bulky, because of the versatility thatthe pneumatic systems provide. LÄS MER

  4. 3. Condition Based Reliability Evaluation and Maintenance Strategy for Battery Energy Storage System

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

    Författare :Novalie Hou; [2022]
    Nyckelord :Battery Energy Storage System; Reliability Evaluation; Maintenance Strategy; Batterienergilagringssystem; Tillförlitlighets Evaluering; Underhållsstrategi;

    Sammanfattning : The electrical grid balances production capacity and demand in real-time. With an increased demand for renewable energy sources, challenges such as stability of the grid, the balance between generation and demand, and power quality occur. LÄS MER

  5. 4. Design and Development of a Data Acquisition and Communication System for Point Absorber Tracking

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Balakrishnan Kannan; [2021]
    Nyckelord :Data Acquisition System; Raspberry Pi; Controller; Processor; Wave buoy; Lysekil; wave energy; measurements; IMU; GPS; Strain gauge; force; Solar energy; Battery; communication; 4G; internet; Remote tracking; Shell; Python;

    Sammanfattning : The recent trend in generating energy from the waves has led to several advancements in the methods and the various research is conducted across the world, to study the behaviour of point absorbers on the waves. The point absorbers such as wave buoys are designed to move according to the waves and the generator that is mechanically coupled with the buoys, generate electricity. LÄS MER

  7. 5. Evaluating the roll performance of a hydraulic-interconnected suspension system for an electric bus

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

    Författare :Dinesh Ramachandran; [2021]
    Nyckelord :Electric bus; Centre of Gravity; Roll gradient; Hydro-pneumatic suspension; Multi-body simulations; Co-simulation; Elektrisk buss; Tyngdpunkt; krängningsgradient; Hydro-pneumatisk fjädring; Flerkroppssimuleringar; Co-simulering;

    Sammanfattning : Electric buses often have batteries installed on the roof structure to have a better space utilization. This increases the height of the centre of gravity of the vehicle, affecting its roll stability. The existing vehicle setup uses an anti-roll bar to provide the roll stiffness. LÄS MER
