  1. 1. Control of a Hydraulic Hybrid System for Wheel Loaders

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system; Linköpings universitet/Fluida och mekatroniska system

    Författare :Christopher Reichenwallner; Daniel Wasborg; [2019]
    Nyckelord :EMS; Energy management strategy; Rule-based; Hydraulic hybrid; Wheel loader; Construction machinery; SLC; Short loading cycle; Torque converter; Energy recuperation; Energy efficiency; Backward simulation;

    Sammanfattning : In recent years many companies have investigated the use of hybrid technology due to the potential of increasing the driveline’s efficiency and thus reducing fuel consumption. Previous studies show that hydraulic hybrid technology can be favourable to use in construction machinery such as wheel loaders, which often operate in repetitive drive cycles and have high transient power demands.

  2. 2. Design and Fluid Simulation of a Fluidic Growth Chamber

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Pranav Bapat; [2019]
    Nyckelord :;

    Sammanfattning : Filamentous fungi are of interest for biotechnologists particularly because of thefungi’s ability of producing commercial products after undergoing certain industrialprocess. Although because of the complicated and intricate internal mechanism ofthe fungi there are certain aspects which need to be studied to maximize the produc-tion output. LÄS MER

  3. 3. Energy Management of Parallel Hydraulic Hybrid Wheel Loader

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hoang Thai Do; [2018]
    Nyckelord :;

    Sammanfattning : Hybridization of driveline system is one possible solution to increase fuel eciency.In this thesis a parallel hybrid hydraulic wheel loader concept was studied. A highpressure accumulator was added to the system and acted as a second source of energy. LÄS MER

  4. 4. Large Eddy Simulation of Turbulent Flow over a Backward-Facing Step

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Edmond Shehadi; [2018]
    Nyckelord :;

    Sammanfattning : This work studies the effect of grid resolution and subgrid scale modeling on the predictive accuracy of Large Eddy Simulation. In particular, the problems considered are: turbulent flow over a backward-facing step and fully-developed turbulent channel flow. LÄS MER

  5. 5. Fast Real-Time MPC for Fighter Aircraft

    Master-uppsats, Linköpings universitet/Reglerteknik; Linköpings universitet/Reglerteknik

    Författare :Amanda Andersson; Elin Näsholm; [2018]
    Nyckelord :MPC; fast MPC; explicit MPC; fighter; aircraft; neural network; model predictive control; interior-point method;

    Sammanfattning : The main topic of this thesis is model predictive control (MPC) of an unstable fighter aircraft. When flying it is important to be able to reach, but not exceed the aircraft limitations and to consider the physical boundaries on the control signals. LÄS MER
