  1. 1. Linearization Based Model Predictive Control of a Diesel Engine with Exhaust Gas Recirculation and Variable-Geometry Turbocharger

    University essay from Linköpings universitet/Fordonssystem

    Author : Jonatan Gustafsson; [2021]
    Keywords : MPC; Model Predictive Control; LMPC; Linearization Based MPC; SLMPC; Successive Linearization Based MPC; Reference Generator; CasADi; EGR; Exhaust Gas Recirculation; VGT; Variable-Geometry Turbocharger; Diesel Engine; Heavy Duty Diesel Engine; Automatic Control; WHTC; World Harmonized Transient Cycle; Direct Multiple Shooting;

    Abstract : Engine control systems aim to ensure satisfactory output performance whilst adhering to requirements on emissions, drivability and fuel efficiency. Model predictive control (MPC) has shown promising results when applied to multivariable and nonlinear systems with operational constraints, such as diesel engines. READ MORE

  3. 2. 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

  4. 3. Impact of Pressure Pulsations on Diesel Air Path Control and Compensation Measures

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : NISHANT DHANORE; [2019]
    Keywords : ;

    Abstract : Stricter pollution norms have led to increased efforts to achieve lower emissions. Exhaust Gas Re-circulation (EGR) is a well known measure to reduce NOx internally in the engine. In order to achieve better performance of an engine in terms of emissions it is very essential to control the flow of exhaust gases through EGR valve. READ MORE

  5. 4. Compressible Flow Modeling with Combustion Engine Applications

    University essay from Linköpings universitet/Fordonssystem

    Author : Carl Vilhelmsson; [2017]
    Keywords : Compressible; Flow; Modeling; Combustion; Engine; Throttle; EGR; Wastegate; Valves; Gas;

    Abstract : The high demands on low fuel consumption and low emissions on the combustion engines of both today, and the future, is highly dependent on advanced control systems in order to fulfill these demands. The control systems and strategies are based on models which describe the physical system. READ MORE

  6. 5. Model Based Control of Throttle, EGR and Wastegate : A System Analysis of the Gas Flows in an SI-Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : Henrik Andersson; [2017]
    Keywords : Model; Control; SI-engine; gas-flow; system analysis;

    Abstract : Due to governmental requirements on low exhaust gas emissions and the drivers request of fast response, it is important to be able to control the gas flow in a spark ignited engine accurately. The air into the cylinder is directly related to the torque generated by the engine. READ MORE
