  1. 11. Controlling a Hydraulic System using Reinforcement Learning : Implementation and validation of a DQN-agent on a hydraulic Multi-Chamber cylinder system

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : David Berglund; Niklas Larsson; [2021]
    Keywords : Gear selection; reinforcement learning; machine learning; DQN; neural network; multi chamber cylinder; Digital hydraulics; hydraulics; Matlab; Simulink; Hopsan; hydraulic system validation;

    Abstract : One of the largest energy losses in an excavator is the compensation loss. In a hydraulic load sensing system where one pump supplies multiple actuators, these compensation losses are inevitable. READ MORE

  2. 12. Electrically powered manoeuvring of water jets

    University essay from Uppsala universitet/Industriell teknik

    Author : Joel Engström; [2021]
    Keywords : Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

    Abstract : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.

    Author : Nachiketh Lingachari Acharya; Saurav Dasgupta; [2021]
    Keywords : ;

    Abstract : There is an increasing stringency in the emission legislation within the transport industry along with ambitious performance demands from the customer side. These have pushed the vehicle manufacturers and relevant component suppliers to develop and integrate a wide portfolio of engine technologies. READ MORE

  5. 15. A GENeric Internal Combustion Engine model : LiU-Genie

    University essay from Linköpings universitet/Fordonssystem

    Author : Oskar Lind Jonsson; [2021]
    Keywords : ;

    Abstract : As the demand for control in modern vehicles grows, models are needed to develop a better understanding of processes and engine behavior. The thesis contributes with a generic extended MVEM with SI and CI as well as VVA compatibility and modeling structure using MATLAB/Simulink environment. READ MORE
