  1. 1. Ensuring safe docking maneuvers on floating platform using Nonlinear Model Predictive Control (NMPC)

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Federico Gatti; [2024]
    Nyckelord :Robotics; Space Engineering; Docking Maneuvers; Floating Platforms; Nonlinear MPC; MPC; Barrier function; PWM;

    Sammanfattning : Docking maneuvers are a relevant part of the modern space mission, requiring precision and safety to ensure the success of the overall mission. This thesis proposes using a non-linear Model Predictive Control (MPC) as a controller with various constraints to ensure safe docking maneuvers for a satellite. LÄS MER

  3. 2. Portfolio Risk Modelling in Venture Debt

    Master-uppsats, KTH/Matematisk statistik

    Författare :John Eriksson; Jacob Holmberg; [2023]
    Nyckelord :Startup Default Probability; Venture Debt; Gaussian Copula; Value-at-Risk; Expected Shortfall; Exposure at Default; Loss Given Default; Forecast; Linear Dynamic System; ARIMA Time Series; Monte Carlo Simulation; Linear Regression; Central Limit Theorem;

    Sammanfattning : This thesis project is an experimental study on how to approach quantitative portfolio credit risk modelling in Venture Debt portfolios. Facing a lack of applicable default data from ArK and publicly available sets, as well as seeking to capture companies that fail to service debt obligations before defaulting per se, we present an approach to risk modeling based on trends in revenue.

  4. 3. Grey-box Modeling of Hydropower Plants for Improved Frequency Regulation : Evaluation of Double-Regulated Hydropower Turbines for Fulfillment of the New FCR-requirements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Karolina Engström; Rebecca Waldenfjord; [2023]
    Nyckelord :Double-regulated hydroturbines; Grey-box modeling; FCR-requriements; Frequency contaminent reserve; Hydropower modeling; Dynamic stability; Dynamic performance;

    Sammanfattning : Over the last decades, the frequency on the Nordic electrical power grid has deteriorated. Therefore, new stricter requirements are developed for the hydropower delivering regulating active power on the Frequency Containment Reserve market (FCR). LÄS MER

  5. 4. Deep Reinforcement Learning on Social Environment Aware Navigation based on Maps

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

    Författare :Victor Sanchez; [2023]
    Nyckelord :Deep Reinforcement Learning; Environment-aware navigation; Robotics; Artificial Intelligence; Apprentissage par renforcement profond; Navigation consciente de l’humain; Intelligence Artificielle; Robotique; Djup Förstärkande Inlärning; Människomedveten navigering; Robotik; Artificiell Intelligens;

    Sammanfattning : Reinforcement learning (RL) has seen a fast expansion in recent years of its successful application to a range of decision-making and complex control tasks. Moreover, deep learning offers RL the opportunity to enlarge its spectrum of complex fields. LÄS MER

  7. 5. Dispatch Optimization of the TES.POD Cluster using Mixed-Integer Linear Programming Models

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Ivar Wikander; [2023]
    Nyckelord :Optimization; Electricity dispatch; Mixed Integer Linear Programming; MILP; Solar PV; Microgrid; Energy Transition; Optimering; Solkraft; Linjär programmering; Elnät;

    Sammanfattning : With increasing shares of variable renewable energy sources in the power mix, the need for energy storage solutions is projected to increase as well. Storage can in such combined systems help mitigate the issues with relying on intermittent sources by time-shifting the supply and smoothing out frequency fluctuations, to name some examples. LÄS MER
