  1. 16. Iterative methods and convergence for the time-delay Lyapunov equation

    University essay from KTH/Numerisk analys, NA

    Author : Lena Leitenmaier; [2016]
    Keywords : ;

    Abstract : The delay Lyapunov equation is a matrix boundary value problem arising in the characterization of many properties of time-delay systems, for example stability analysis. Its numerical treatment is challenging. For the special case of single-delay systems, a new algorithm based on a delay free formulation has recently been proposed. READ MORE

  3. 17. An Multivariable Approach for the Chemostat Model

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Sebastian Thörngren; [2016]
    Keywords : ;

    Abstract : We use a multivariable approach to study the Chemostat model for a food chain. Using a Lyapunov function we reduce the system to a two-dimensional system.We then find isoclines and equilibrium points using a change of variables and the implicit function theorem. READ MORE

  4. 18. Design, Modeling and Control of an Octocopter

    University essay from KTH/Optimeringslära och systemteori

    Author : Oscar Oscarson; [2015]
    Keywords : ;

    Abstract : This master’s thesis project from the Department of Mathematics at KTH, Royal Institute of Technology, Stockholm, Sweden was carried out at Saab Dynamics, Linköping, Sweden. In this thesis, an octocopter was studied, which is a multirotor vehicle, a rotorcraft with more than two rotors. READ MORE

  5. 19. Model Based Automatic Tuning and Control of a Three Axis Camera Gimbal

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Henric Edlund; [2015]
    Keywords : system identification; feedback linearisation; camera gimbal;

    Abstract : A gimbal is a pivoted device that decouples movements of a platform from its payload. The payload is a camera which must be stabilized to capture video without motion disturbances. A challenge with this type of gimbal is that a wide span of cameras with different sizes and weights can be used. READ MORE

  6. 20. Investigation of the Dynamics and Modeling of a Triangular Quadrotor Configuration

    University essay from KTH/Aerodynamik

    Author : Toni Axelsson; [2014]
    Keywords : ;

    Abstract : In this paper the dynamics of a new type of quadrotor configuration, called Y4, is investigated. The configuration is proposed to be more energy efficient than the traditional design where four rotors are placed around the center of the aircraft frame. READ MORE
