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

4. 3. Model Predictive Climate Control for Electric Vehicles

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Erik Norstedt; Olof Bräne; [2021]
   Keywords : MPC; model predictive control; climate control; electric vehicle; battery; thermal management; electrified vehicle; battery electric vehicle; nonlinear MPC; custom cost functions; elfordon; temperaturreglering;

   Abstract : This thesis explores the possibility of using an optimal control scheme called Model Predictive Control (MPC), to control climatization systems for electric vehicles. Some components of electric vehicles, for example the batteries and power electronics, are sensitive to temperature and for this reason it is important that their temperature is well regulated.

5. 4. 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

6. 5. Modelling and Trajectory Planning for a Small-Scale Surface Ship

   University essay from Linköpings universitet/Reglerteknik

   Author : Gustav Zetterqvist; Fabian Steen; [2021]
   Keywords : Marine vessel; Ship; Modelling; Model estimation; Trajectory planning; Optimal control;

   Abstract : Autonomous ships are one way to increase safety at sea and to decrease environmental impact of marine traveling and shipping. For this application, a good representation of the environment and a physical model of the ship are vital components. READ MORE
