  1. 1. Design and Implementation of a Strategy for Path Tracking on Autonomous Heavy-Duty Vehicles

    University essay from Linköpings universitet/Fordonssystem

    Author : Oscar Törnroth; Truls Nyberg; [2018]
    Keywords : Control Engineering; Control Architecture; Autonomous Vehicles; Heavy-Duty Vehicles; Motion Control; Path Tracking; Curvature Tracking; Lateral Control; Steering Systems; Feedforward Control Systems; System Identification; Understeering;

    Abstract : In this thesis, a combined feedforward and feedback controller for improved path tracking on autonomous heavy-duty vehicles is designed and implemented. The steering wheel is controlled in order to follow a reference curvature, computed by a higher-level MPC, responsible for minimizing the distance to a planned path. READ MORE

  3. 2. Energy Management Strategy of a Hybrid Electric Vehicle for Shell Eco-marathon

    University essay from KTH/Maskinkonstruktion (Inst.)

  4. 3. Attitude and Orbit Control During Deorbit of Tethered Space Debris

    University essay from KTH/Farkost och flyg

    Author : Linus Flodin; [2015]
    Keywords : space debris mitigation; deorbit; tethered satellites; mathematical modeling; attitude and orbit control system; LQG control; PID control; switched control;

    Abstract : Due to the unsustainable space debris environment in Low Earth Orbit, debris objects must be removed to ensure future safe satellite operations. One proposed concept for deorbiting larger space debris objects, such as decommissioned satellites or spent upper rocket stages, is to use a chaser spacecraft connected to the debris object by an elastic tether, but the required technology is immature and there is a lack of flight experience.

  5. 4. Simulating MPC Controlled Lime Injection for the Flue-gas Treatment at Fortum's Thermal Power Plant

    University essay from KTH/Reglerteknik

    Author : Joacim Sundberg; [2015]
    Keywords : ;

    Abstract : The aim of this thesis is to investigate the possibility to improve the separation of HCl and SO2 in the dry ue-gas treatment for boiler #3 at Fortum's thermal power plant in Hogdalen; by using a model predictive control instead of a PID controller to govern the slaked lime injection. To achieve this an ARMAX model was derived using MATLAB's System Identi cation Toolbox and measurements of the incoming and outgoing levels of HCl, SO2 and the speed of the injection motor.

  6. 5. Simulation and Testing of Energy Efficient Hydromechanical Drivlines for Construction Equipment

    University essay from Linköpings universitet/Fluida och mekatroniska system; Linköpings universitet/Tekniska högskolan

    Author : Viktor Larsson; L. Viktor Larsson; [2014]
    Keywords : hydraulic; power-split; hydrostatic; PST; HST; mechatrinics; oil; volvo; backhoe; transmission; harware-in-the-loop; simulation; hopsan; control; PID; feed forward; HWIL; fluid power; Hydraulik; power-split; hydrostat; PST; HST; mekatronik; olja; volvo; backhoe; transmission; harware-in-the-loop; simulering; hopsan; reglering; PID; framkoppling; HWIL;

    Abstract : Increased oil prices and environmental issues have increased a need of loweringthe emissions from and the fuel consumption in heavy construction machines. Anatural solution to these issues is a lowered input power through downsizing ofthe engine. READ MORE
