  1. 1. Real-time Optimal Braking for Marine Vessels with Rotating Thrusters

    University essay from KTH/Matematik (Avd.)

    Author : Sigurlaug Rún Jónsdóttir; [2022]
    Keywords : Nonlinear optimization; nonlinear optimal control; numerical optimal control; real-time solution; optimal braking; receding horizon; modeling; ship model; propeller forces; rudder forces; direct multiple shooting method; discretization;

    Abstract : Collision avoidance is an essential component of autonomous shipping. As ships begin to advance towards autonomy, developing an advisory system is one of the first steps. An advisory system with a strong collision avoidance component can help the crew act more quickly and accurately in dangerous situations. READ MORE

  3. 2. 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

  4. 3. An Optimal Control Toolbox for MATLAB Based on CasADi

    University essay from Linköpings universitet/Fordonssystem

    Author : Viktor Leek; [2016]
    Keywords : Optimal Control Direct Collocation Multiple Shooting Casadi Matlab Hybrid Vehicle;

    Abstract : Many engineering problems are naturally posed as optimal control problems. It may involve moving between two points in the fastest possible way, or to put a satellite into orbit with minimum energy consumption. Many optimal control problems are too difficult to be solved analytically and therefore require the use of numerical methods. READ MORE
