1. 1. 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

3. 2. Development of Vessel Phantoms for Ultrasound Methods

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Benjamin Meirza; [2018]
   Keywords : Longitudinal movement of the arterial wall; Vasa vasourom; Micro vessles; SEBS; Ultrasound phantom.; Technology and Engineering;

   Abstract : Phantoms mimicking the specific mechanical and acoustic properties of human tissues are essential in the development and evaluation of novel ultrasound methods. In this work, various ultrasound phantoms are proposed to be used in the development of ultrasound methods to investigate the arterial walls longitudinal movements influence on the vasa vasorum circulation.

4. 3. Design and Optimization of Controllers for an Electro-Hydraulic System

   University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska högskolan

   Author : Simon André; [2014]
   Keywords : Electro-Hydraulic; EH; Controllers; Control strategies; Proportional-Integral-Derivative; PID; Cascade; Feed forward; Linear Quadratic; LQ; Model Predictive Control; MPC;

   Abstract : Electro-Hydraulic (EH) systems are commonly used in the industry for applications that require high power-weight ratios and large driving forces. The EH system studied in this master thesis have recently been upgraded with new hardware components and as a part of this upgrade a new controller was requested. READ MORE

5. 4. Reduction of oil pump losses in automatic transmissions

   University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska högskolan

   Keywords : oil pump; vane pump; gear pump; electric pump; variable displacement; automatic transmission; pump; oil; control;

   Abstract : In the vehicle industry it is of great interest to reduce the emissions and lower the fuel consumption.Up to now a lot of effort has been put into increasing the efficiency of the engine,but it starts to get expensive to keep improving the engine. READ MORE

6. 5. Modelling and Simulation of a Power Take-off in Connection with Multiple Wave Energy Converters

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Ashkan Ghodrati; Ahmed Rashid; [2014]
   Keywords : Wave power; power take-off; wave energy converter; weight accumulator; power capture control; planetary gearbox; modeling and simulation ;

   Abstract : The objective of this thesis is to develop a model that will integrate multiple buoys to a power take-off hub. The model will be derived using a time domain analysis and will consider the hydraulic coupling of the buoys and the power take-off. The derived model is reproduced in MATLAB in order to run simulations. READ MORE
