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

    University essay from KTH/Skolan för teknikvetenskap (SCI)

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

    Abstract : 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. READ MORE

  3. 2. A Trust-Region Method for Multiple Shooting Optimal Control

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Shaohui Yang; [2022]
    Keywords : Trust Region Method; Optimal Control; Model Predictive Control; Sequential Quadratic Programming; Quadratic Programming; Inde_nte Hessian; Mobile Robots; Trust Region Method; Optimal Control; Model Predictive Control; Sekventiell kvadratisk programmering; kvadratisk programmering; obestämd hessian; mobila robotar;

    Abstract : In recent years, mobile robots have gained tremendous attention from the entire society: the industry is aiming at selling more intelligent products while the academia is improving their performance from all perspectives. Real world examples include autnomous driving vehicles, multirotors, legged robots, etc. READ MORE

  4. 3. Subsampling Strategies for Bayesian Variable Selection and Model Averaging in GLM and BGNLM

    University essay from Stockholms universitet/Statistiska institutionen

    Author : Jon Lachmann; [2021]
    Keywords : Bayesian model averaging; subsampling; GLM; BGNLM; IRLS; Optimisation;

    Abstract : Bayesian Generalized Nonlinear Models (BGNLM) offer a flexible alternative to GLM while still providing better interpretability than machine learning techniques such as neural networks. In BGNLM, the methods of Bayesian Variable Selection and Model Averaging are applied in an extended GLM setting. READ MORE

  5. 4. Conceptual Design of an Air-Launched Three-Staged Orbital Launch Vehicle

    University essay from KTH/Rymdteknik

    Author : Måns Rasmussen; [2021]
    Keywords : Air-launched; Launch Vehicle; Three-staged; Rocket; Sun-Synchronous orbit; Solid propellant; Liquid propellant; Trajectory optimization; Nonlinear programming; JAS 39 Gripen; Fighter aircraft; Luftlanserad; Trestegsraket; Solsynkron bana; Fast bränsle; Flytande bränsle; Bananalys; Icke-linjär optimering; JAS 39 Gripen; Jaktflygplan;

    Abstract : The objective of this study was to design a launch vehicle capable of deploying a nanosatellite into a Sun-synchronous orbit at 500 km orbital altitude from the JAS 39E/F Gripen fighter aircraft. This was achieved by first performing theoretical calculations for the required nozzles and solid propellant grain configurations for the first two solid stages, followed by the necessary liquid propellant configuration for the third stage.

  6. 5. Numerical optimization ofsolar sail trajectories to Mars

    University essay from KTH/Rymdteknik

    Author : Guillermo Martínez Cabalga; [2020]
    Keywords : ;

    Abstract : Typical propulsion systems for space transportation involve the ejectionof mass for momentum gain. Solar sails remove the requirement forpropellant mass by obtaining their momentum from solar photons, whichrequires large surface area and very low mass. READ MORE
