  1. 1. Improving charging scheduling of public transport electric buses

    Master-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Franz Bamberg; Anna Hassler; [2023]
    Nyckelord :Peak load; electricity trading; spot prices; electric buses; bus transport operator; battery energy storage system; charging scheduling; Technology and Engineering;

    Sammanfattning : Title: Improving charging scheduling of public transport electric buses Authors: Anna Hassler & Franz Bamberg Supervisor: Johan Marklund, Lund University Background: This thesis focuses on a Swedish BTO that operates EB fleets. For companies investing in electrification, record-high and volatile electricity prices, present challenges and creates a need to improve the charging scheduling of EBs to reduce costs. LÄS MER

  3. 2. Optimizing First-Order Method Parameters via Differentiation of the Performance Estimation Problem

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Anton Åkerman; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis treats the problem of finding optimal parameters for first-order optimization methods. In part, we use the Performance Estimation Problem (PEP), a framework for convergence analysis of first-order optimization methods. LÄS MER

  4. 3. Optimization over nonnegative matrix polynomials

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Daniel Cederberg; [2023]
    Nyckelord :Proximal methods; nonnegative polynomials; Bregman proximal operator; Itakura-Saito distance; spectral estimation; functional connectivity analysis.;

    Sammanfattning : This thesis is concerned with convex optimization problems over matrix polynomials that are constrained to be positive semidefinite on the unit circle. Problems of this form appear in signal processing and can often be solved as semidefinite programs (SDPs). LÄS MER

  5. 4. Real-time Model Predictive Control with Complexity Guarantees Applied on a Truck and Trailer System

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Edvin Bourelius; [2022]
    Nyckelord :Real-time; Model Predictive Control; Quadratic Programing; Active-set method; Complexity Certification; Truck; Trailer;

    Sammanfattning : In model predictive control an optimization problem is solved in every time step, which in real-time applications has to be solved within a limited time frame. When applied on embedded hardware in fast changing systems it is important to use efficient solvers and crucial to guarantee that the optimization problem can be solved within the time frame.
