  1. 1. Real time control of an active pendulum arm suspension system for a downscaled XT28 forwarder model

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Niclas Määttä; Adam Westermark; [2023]
    Keywords : mechatronics; offset-free MPC; MPC; LQR; XT28; forwarder; pendulum arm; forestry; mekatronik; offset-free MPC; MPC; LQR; XT28; skotare; pendelarm; skogsbruk;

    Abstract : A forwarder named XT28 has been developed in joint collaboration between eXtractor AB, Skogforsk AB, KTH, Linköpings Unversity, Sveaskog, and Bosch Rexroth. The forwarder is equipped with six hydraulic active suspension pendulum arms. READ MORE

  3. 2. Hanging Load Mock-Up For Experimental Setup To Test Flight System Stability

    University essay from Uppsala universitet/Signaler och system

    Author : Anthony Gundstedt; [2023]
    Keywords : drone; hanging; variable length; mixer matrix; PID; controller; microcontroller; RC; Telnet; I2C; FrSKY; Sbus; S.bus; Forestry; AirForestry; Swing; anti-swing; IMU; filter;

    Abstract : Can we reduce disturbance, swing, and errors by delegating some of the tasks to a subsystem on the tool hanging from a drone to gain precision and dependability? This project covers developing and implementing a user-controlled prototype with an automatic control system and gripper for functionality and controlled movement in 5 DOF. AirForestry is developing a new way of working in the forestry business to provide a greener and healthier solution for the soil and the environment. READ MORE

  4. 3. Autonomous Landing of an Unmanned Aerial Vehicle on an Unmanned Ground Vehicle using Model Predictive Control

    University essay from Linköpings universitet/Institutionen för systemteknik

    Keywords : Model predictive control; MPC; Unmanned aerial vehicle; UAV; Unmanned ground vehicle; UGV; Path planning; Vehicle dynamics; Autonomous systems; Autonomous landing; Quadcopter; Gazebo; ROS;

    Abstract : The research on autonomous vehicles, and more specifically cooperation between autonomous vehicles, has become a prominent research field during the last cou- ple of decades. One example is the combination of an unmanned aerial vehicle (UAV) together with an unmanned ground vehicle (UGV). READ MORE

  5. 4. Obtaining Pitch Control for Unmanned Aerial Vehicle Through System Identification

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

    Author : Lucia Karens; Tawsiful Islam; [2022]
    Keywords : pitch control; flight tests; unmanned aerial vehicles UAV ; system identification; PID control;

    Abstract : This study aimed to develop and evaluate a method to obtain a proportional-integral-derivative (PID) controller. The controller is for a control surface that controls pitch motion, by using data from flight tests with an unmanned aerial vehicle (UAV). READ MORE

  6. 5. Electric Propulsion for a High Altitude Unmanned Aerial Vehicle

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

    Author : Jacob Hjort Friderichsen; David Jönsson; [2022]
    Keywords : Electric Propulsion; UAV; ALPHA; Electronic Speed Controller; BLDC Motor; Propeller;

    Abstract : The catalogue of observational platforms for space and atmospheric research can be expanded by utilising drones equipped with specialised instrumentation and capable of flying at high altitudes. In this project the requirements for an electric propulsion system applicable to the KTH Royal Institute of Technology ALPHA project are evaluated. READ MORE
