  1. 1. Enhancing Servo System Performance : Robust Nonlinear Deadbeat Predictive Current Control for Permanent Magnet Synchronous Motors

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

    Författare :Xingyu Zhao; [2023]
    Nyckelord :keywords here: Deadbeat Predictive Current Control; Permanent Magnet Synchronous Motor; Flux Linkage Nonlinearity; Parameter Inaccuracies; Nonlinear Feedforward Compensation; Delayed Integral Action.; Deadbeat-prediktiv strömreglerin; Permanenta magnet-synkronmotorn; Ickelinjäriteter i flödeslänkningen; Felaktigheter i parametrar; Icke-linjär framåtmatningskompensation; Fördröjd integralåtgärd.;

    Sammanfattning : The Permanent Magnet Synchronous Motor (PMSM, also known as the servo motor) is a crucial component within robotic servo systems. To optimally respond to the torque demands sent from the high-level motion controller, the PMSM current controller must track the reference with speed and precision. LÄS MER

  3. 2. From Topology Optimized Concept to Detailed Design via Implicit-based Geometries and Non-linear Finite Element Analysis

    Uppsats för yrkesexamina på avancerad nivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Jonatan Gripenberth; [2023]
    Nyckelord :Topologioptimiering; Implicita kroppar; Arbetsflöde; Icke-linjär finita element analys;

    Sammanfattning : A workflow to go from topology optimized concept to a detailed design was created in this thesis. This was done through the use of Implicit-based geometries and Non-linear finite element analysis. LÄS MER

  4. 3. Applying Nonlinear Mixed-Effects Modeling to Model Patient Flow in the Emergency Department : Evaluation of the Impact of Patient Characteristics on Emergency Department Logistics

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Umberto Rosamilia; [2022]
    Nyckelord :Emergency Department; Nonlinear Mixed-Effects Modeling; Healthcare Logistics; Patient Flow Modeling; Patient Pathways; Markov Process; Akutmottagning; Icke-Linjär Blandad Effektmodellering; Vårdlogistik; Patientflödesmodellering; Patientflöde; Markovprocess;

    Sammanfattning : Emergency departments are fundamental for providing high-quality care, and their operations directly impact the logistics of the hospitals in their entirety. Poor emergency department performance leads to delays, prolonged hospitalization, and improper allocation of resources, reducing the quality of the provided care and increasing costs. LÄS MER

  5. 4. Optimization of Collateral Allocation for Corporate Loans : A nonlinear network problem minimizing the expected loss in case of default

    Master-uppsats, KTH/Matematik (Avd.)

    Sammanfattning : Collateral management has become an increasingly valuable aspect of credit risk. Managing collaterals and constructing accurate models for decision making can give any lender a competitive advantage and decrease overall risks. LÄS MER

  7. 5. Stability of building structures using NLFEA including second order effects : Applications with the software ATENA-GiD

    Master-uppsats, KTH/Betongbyggnad

    Författare :Alexandros Petkoglou; [2021]
    Nyckelord :Non-linear analysis; second order effects; prefabricated buildings; ATENA; GiD; slip connection; Icke-linjär analys; andra ordnings effekter; förtillverkade byggnader; prefabricerade byggnader; ATENA; GiD; glidkoppling;

    Sammanfattning : In Sweden, prefabrication in the construction industry is a very common system. In prefabricated structures, there are various kinds of connections and generally many hinged connections. Therefore, it is of high interest to study the behavior of the prefabricated buildings in relation to the connections. LÄS MER
