  1. 1. Study of the vibronic mixing in chlorophylls with multidimensional spectroscopy

    L3-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Ignacio Martínez Casasús; [2021]
    Nyckelord :Two-dimensional spectroscopy; Ultrafast spectroscopy; Chlorophyll a; Chlorophylls; Photosynthesis; Light harvesting; Vibronic mixing; Quantum coherence; Chemical physics; Chemistry;

    Sammanfattning : Chlorophylls comprise one of the most important families of molecules for the photosynthetic process. Chlorophyll-like molecules have been classically interpreted under the Gouterman model, being thought to feature two independent transitions, Qy(S1) and Qx(S2). LÄS MER

  2. 2. Robust control system development forVTOL-to-fixed wing flight transition withthe EcoSoar UAV : A masters thesis in Automatic Control

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Robert Hedman; [2020]
    Nyckelord :drone; UAV; thesis; automatic; control; VTOL;

    Sammanfattning : A non switching, non linear, quaternion based attitude P2 controller, together with a sensitivitynormalizing function for the control surfaces has been simulated and implemented on a flying fixedwing with non vectored engines. In simulations the controller worked well in all flight modes,hovering, transition and flying, and also rejected a simple wind disturbance in all modes. LÄS MER

  3. 3. Iterative Learning Control for Preparative Chromatography

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Daniel Espinoza; [2020]
    Nyckelord :Chemical Engineering; Kemiteknik; Chromatography; Automatic Process Control; Iterative Learning Control; ILC; Simulation; Protein Purification; Python; Ion-Exchange; Automation; Batch Processing; Downstream Processing; Technology and Engineering;

    Sammanfattning : There is a desire for a fully automated downstream process in pharmaceutical protein production. One part of the downstreaming process is preparative chromatography. A good separation between the product and other proteins, as well as good productivity, are desired. LÄS MER

  4. 4. Evaluation of Model-Based Design Using Rapid Control Prototyping on Forklifts

    Master-uppsats, Linköpings universitet/Reglerteknik; Linköpings universitet/Reglerteknik

    Författare :Lovisa Jansson; Amanda Nilsson; [2019]
    Nyckelord :Rapid Control Prototyping; Model-Based Design; Forklift; Automatic control; Speedgoat; Model Predictive Control; MPC; P Controller; Models; Simulink; Matlab; Minimum Jerk Trajectory;

    Sammanfattning : The purpose of this thesis is to evaluate Rapid Control Prototyping which is apart of the Model-Based Design concept that makes it possible to convenientlytest prototype control algorithms directly on the real system. The evaluation ishere done by designing two different controllers, a gain-scheduled P controllerand a linear Model Predictive Controller (mpc), for the lowering of the forks of aforklift. LÄS MER

  5. 5. Utveckling av Reglersystem för ett Labyrintspel : Modellbaserad design i praktiken

    Master-uppsats, Linköpings universitet/Reglerteknik; Linköpings universitet/Reglerteknik

    Författare :Mikael Nådin; Kristian Ericsson; [2019]
    Nyckelord :Automatic Control Systems; Labyrinth Game; Modelbased design;

    Sammanfattning : This thesis evaluates two automatic control systems, PID and LQ, for the purpose of controlling the steel marble in a Brio labyrinth game. The objective has been for these automatic control strategies to bring the marble through the labyrinth and examine how well they handle this problem. LÄS MER
