  1. 1. Frequency Stabilization in low Inertia Systems With Battery Power Injections

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

    Författare :Leif Lundin; [2023]
    Nyckelord :;

    Sammanfattning : The challenges for the power system of the future becomes increasingly larger when large amountsof renewable energy sources are integrated, and when conventional forms of power such asnuclear power are phased out. This results in a greater difficulty in quickly deploying FrequencyContainment Reserves in the event of of power balance disturbance, to stabilize frequency andvoltage. LÄS MER

  4. 3. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Jannek Hansen; [2021]
    Nyckelord :Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Sammanfattning : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. LÄS MER

  5. 4. Modeling and Evaluation of Turret Control Systems for Main Battle Tanks

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

    Författare :Mikael Lyth; [2021]
    Nyckelord :Main Battle Tank; PID control; Sliding Mode Control; Model Predictive Control; Two-axis gimbal system; Stridsvagn; PID reglering; SMC; Prediktionsreglering; Tvåaxligt gimbalsystem;

    Sammanfattning : The aim of the thesis was to implement and compare control methods in a model of a main battle tank. Three controllers were implemented in a two axis gimbal model and their performances were compared. LÄS MER

  7. 5. Stabilization of Constant Power Loads Using Model Predictive Control

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

    Författare :Mikael Glamheden; [2020]
    Nyckelord :;

    Sammanfattning : This thesis considers stabilization of constant power loads (CPLs) fed by a dcpower source through an input filter, using model predictive control (MPC).Train propulsion systems generally utilize electrical motors whose output torqueis tightly regulated by power converters. Often, these systems behave as CPLs. LÄS MER
