  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

  2. 2. Spectral broadening of 4 mJ femtosecond pulses using a bulk multi-pass cell

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

    Författare :Saga Westerberg; [2023]
    Nyckelord :Lasers; Ultrashort; Nonlinear Optics; femtosecond; Multi-Pass Cell; Spectral broadening; pulse post-compression; Self phase modulation; Physics and Astronomy;

    Sammanfattning : Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index. LÄS MER

  3. 3. Model Predictive Climate Control for Electric Vehicles

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Erik Norstedt; Olof Bräne; [2021]
    Nyckelord :MPC; model predictive control; climate control; electric vehicle; battery; thermal management; electrified vehicle; battery electric vehicle; nonlinear MPC; custom cost functions; elfordon; temperaturreglering;

    Sammanfattning : This thesis explores the possibility of using an optimal control scheme called Model Predictive Control (MPC), to control climatization systems for electric vehicles. Some components of electric vehicles, for example the batteries and power electronics, are sensitive to temperature and for this reason it is important that their temperature is well regulated.

  4. 4. Comparison of control strategies for manipulating a Hydrobatic Autonomous Underwater Vehicle

    Master-uppsats, KTH/Mekatronik

    Författare :Chariklia Panteli; [2021]
    Nyckelord :Autonomous Underwater Vehicle; AUV; Gripper; Manipulator; Controlcomparison; Linear Quadratic Regulator; LQR; PID; Model Predictive Controller; MPC; Autonomt undervattensfordon; AUV; Gripper; Manipulator; Kontrolljämförelse; Linjär kvadratisk regulator; LQR; PID; Modell Predictive Controller; MPC;

    Sammanfattning : This master thesis project is focused on the development of an LQR controller and its comparison with other controllers (PID and MPC), in order to successfully control an Autonomous Underwater Vehicle manipulation system. The modelling of the manipulator was performed first in Matlab and later on in Simulink-Simscape. LÄS MER

  5. 5. Linearization Based Model Predictive Control of a Diesel Engine with Exhaust Gas Recirculation and Variable-Geometry Turbocharger

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Jonatan Gustafsson; [2021]
    Nyckelord :MPC; Model Predictive Control; LMPC; Linearization Based MPC; SLMPC; Successive Linearization Based MPC; Reference Generator; CasADi; EGR; Exhaust Gas Recirculation; VGT; Variable-Geometry Turbocharger; Diesel Engine; Heavy Duty Diesel Engine; Automatic Control; WHTC; World Harmonized Transient Cycle; Direct Multiple Shooting;

    Sammanfattning : Engine control systems aim to ensure satisfactory output performance whilst adhering to requirements on emissions, drivability and fuel efficiency. Model predictive control (MPC) has shown promising results when applied to multivariable and nonlinear systems with operational constraints, such as diesel engines. LÄS MER
