  1. 1. Evaluation of MPC and PI control on a Tribometer : Design and comparison of control methods for a Pin-on-Disc Tribometer

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ehab Ziad Raheem; Tore Malmström; [2023]
    Keywords : Control Theory; MPC; PI; PI-Cascade; Tribometer; Pin-on-Disc; Reglersystem; MPC; PI; PI-Kaskadreglering; Tribometer; Stift-På-Skiva;

    Abstract : This thesis compares Model Predictive Control (MPC) and Proportional-Integral (PI) control in a pin-on-disc tribometer. The tribometer consists of a geared Direct Current (DC) motor driving a flywheel and a voice coil actuating a pin onto the surface of the flywheel. READ MORE

  3. 2. Heuristic control of a small line-following robot : A comparison of different methods

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Neo Gumbel; Omed Khirzia; [2022]
    Keywords : PID; Ziegler-Nichols; Tyreus-Luyben; Heuristic; Line-follower; PID; Ziegler-Nichols; Tyreus-Luyben; Heuristik; Linjeföljare;

    Abstract : A line-follower is a robot that follows a line. Line-followers can be used in industry, mostly for material transportation, but are also raced against each other in competitions. While line-followers used in industry prioritize smooth motion and accuracy, competition-style line-followers prioritize speed around the track. READ MORE

  4. 3. Protection of HVDC Grids Against Blackouts (Simulation)

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

    Author : Amal Al-Ammari; Dinah Atchan; [2021]
    Keywords : High Voltage Direct Current HVDC ; Voltage derivative dv=dt algorithm; Traveling wave algorithm; PSCAD simulation; Multi-terminal grid; Fault detection; Threshold value; Offshore HVDC; DC breaker; Voltage collapse;

    Abstract : In the search for green energy to combat climatechange, a shift from conventional energy sources such as coal,oil, and nuclear towards Renewable Energy Sources (RES) isneeded. This shift poses a threat to the stability of the powergrids as RES do not contribute with rotating mass in the system. READ MORE

  5. 4. Frequency Stability in Future Low Inertia Power Systems With Battery Support

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

    Author : Alessandro Bonetti; Emil Bergvall; [2021]
    Keywords : Battery power support; Frequency Containment Reserves; Fast Frequency Reserves; Low inertia; Renewable Energy Sources;

    Abstract : In the search for green energy to combat climatechange, a shift from conventional energy sources such as coal,oil, and nuclear towards Renewable Energy Sources (RES) isneeded. This shift poses a threat to the stability of the powergrids as RES do not contribute with rotating mass in the system. READ MORE

  6. 5. Stability of a Vision Based Platooning System

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

    Author : Ann Köling; Kristina Kjellberg; [2021]
    Keywords : Adaptive Cruise Control; Aruco markers; Realtime visual tracking; Vehicle platooning; Vision-based control;

    Abstract : The current development of autonomous vehiclesallow for several new applications to form and evolve. One ofthese are platooning, where several vehicles drive closely togetherwith automatic car following. The method of getting informationabout the other vehicles in a platoon can vary. One of thesemethods is using visual information from a camera. READ MORE
