  5. 4. Modelling of Mechanical Flexibilities in Robotic Manipulators and Evaluation of Their Impact on Motion Performance

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Patrik Levin; Daniel Mofors; [2016]
    Nyckelord :;

    Sammanfattning : In order to achieve the best robot performance, the exibilities in the mechanical structures of a robot manipulator needs to be modelled and compensated for, when designing a controller. By examining how each flexible component contribute to the overall dynamic performance, the robot's mechanical design can be altered to optimised performance and minimise cost. LÄS MER

  7. 5. Modeling and Control of a Parallel HEV Powertrain with Focus on the Clutch

    Master-uppsats, Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Författare :Mahdi Morsali; [2015]
    Nyckelord :parallel hybrid electric vehicles; clutch modeling; driveline modeling; torsional vibrations; slipping clutch; energy management; optimization;

    Sammanfattning : Nowadays, the increasing amount of greenhouse gases and diminishing of the existing petroleum minerals for future generations, has led the automotive companies to think of producing vehicles with less emissions and fuel consumption. For this purpose, Hybrid Electric Vehicles (HEVs) have emerged in the recent decades. LÄS MER
