  1. 1. Model-Predictive Control of Gas Exchange in a Gasoline Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : George Jajji; [2021]
    Keywords : Control Engineering; Model Predictive Control; MPC; Gasoline Engine; Gas Exchange;

    Abstract : The process to induct air into engine cylinders, via the air inlet system and cylin-der port valves, is referred to as the "gas-exchange". Control is achieved by theturbo-charger, the intake throttle plate and the variable valve timing (VVT) sys-tem. These actuation systems traditionally use separate control with indepen-dent SISO feedback. READ MORE

  3. 2. Techniques to inject pulsating momentum

    University essay from Luleå tekniska universitet/Strömningslära och experimentell mekanik

    Author : Jelle Kranenbarg; [2020]
    Keywords : Hydro power; Rotating Vortex Rope; Flow control; Fluidic actuator; Synthetic jet actuator; Piston actuator; CFD;

    Abstract : Hydro power plants are an essential part of the infrastructure in Sweden as they stand for a large amount of the produced electricity and are used to regulate supply and demand on the electricity grid. Other renewable energy sources, such as wind and solar power, have become more popular as they contribute to a fossil free society. READ MORE

  4. 3. Evaluation of a digitial displacement pump in a load haul dump application

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Jayasurya Madhusudanan; [2019]
    Keywords : Digital displacement pump; mine loader; energy efficiency; backward simulation; forward simulation; pump losses;

    Abstract : Hydraulics has always been the first choice of actuation in off-road, construction and mining vehicles due to its power density, low cost, built in cooling and lubrication. However, the current state of our environment along with stricter regulations has brought light to newer technologies within hydraulics to improve the existing system. READ MORE

  5. 4. Improved control strategies for primary frequency control in Swedish combined heat and power plants

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Gustav Sondell; [2019]
    Keywords : Technology and Engineering;

    Abstract : A model of the Swedish power plant Mälardalen Energi, developed by Solvina AB was simulated in Dymola with different types of control strategies in order to evaluate if they could improve the operational flexibility of the plant and, thus, its ability to deliver frequency control to the Swedish power grid. Several different control strategies and process modifications were tested and compared to previous simulations done by Solvina. READ MORE

  6. 5. Estimation of Air Mass Flow in Engines with Variable Valve Timing

    University essay from Linköpings universitet/Reglerteknik

    Author : Elina Fantenberg; [2018]
    Keywords : Diesel Engine; Variable Valve Timing; Air Mass Flow;

    Abstract : To control the combustion in an engine, an accurate estimation of the air mass flow is required. Due to strict emission legislation and high demands on fuel consumption from customers, a technology called variable valve timing is investigated. READ MORE
