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

    University essay from Uppsala universitet/Signaler och system

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

    Abstract : 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. READ MORE

  3. 2. Intervallic Semiosis: an Exploration of Valence and Pitch

    University essay from Linnéuniversitetet/Institutionen för psykologi (PSY)

  4. 3. Inclusion of Wind Turbines into Frequency Support Services : Exploring frequency stability issues and comparing regulation power market products

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Oskar Andersson; [2021]
    Keywords : Frequency Containment Reserve; Frequency Restoration Reserve; Fast Frequency Restoration; Synthetic Inertia; Variable Speed Wind Turbine;

    Abstract : There is a trend in Sweden towards increasing the electricity production from renewable energy sources in the electric grid. The increased share of renewables could be seen as essential for Sweden to be able to meet the obligated climate goals. READ MORE

  5. 4. The potential of wind power on the Swedish ancillary service markets

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

    Author : Hannes Wiklund; [2021]
    Keywords : ;

    Abstract : An increasing proportion of variable renewable energy in the Swedish power system is leading to greater needs of system flexibility. A key aspect of handling this is frequency flexibility where actors can either increase or decrease their production or consumption when required. READ MORE
