  1. 1. 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

  5. 4. Modelling, Identification and Control of a Quadrotor Helicopter

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Tammaso Bresciani; [2008]
    Keywords : System Identification; PID Control; VTOL; UAV; Quadrotor; Technology and Engineering;

    Abstract : This thesis work focused on the study of a quadrotor helicopter. The dynamic system modelling and the control algorithm evaluation were carried out. To test the results, a simulator and a real platform were developed. The Newton-Euler formalism was used to model the dynamic system. READ MORE
