    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

  4. 3. A case study of disjunctive programming: Determining optimal motion trajectories for a vehicle by mixed-integer optimization

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Oskar Jagstedt; Elias Vitell; [2023]
    Nyckelord :Optimization; disjunctive programming; integer programming; Gurobi; big-M; nonlinear programming;

    Sammanfattning : This report considers an application of mixed-integer disjunctive programming (MIDP)where a theoretical robot can jump from one point to another and where the number ofjumps is to be minimized. The robot is only able to jump to the north, south, east andwest. LÄS MER
