  1. 1. Accurate Simulation of a Collaborative Robot Arm with Cartesian Impedance Control

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Joel Holmesson; [2021]
    Keywords : Technology and Engineering;

    Abstract : Simulation of systems is used in several fields of science as a tool for safe and resource-efficient testing, as well as a tool for prediction. In this thesis, the goal is to produce an accurate simulation of a collaborative robot arm, together with a controller solution. The robot is supposed to learn and perform contact-rich tasks.

  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. Optimizing a servo drive using Field Oriented Control

    University essay from Uppsala universitet/Solcellsteknik

    Author : Lukas Land; [2021]
    Keywords : antenna; servo; foc; pmsm; vector engine; field oriented control; electrical motor; servo; fältorienterad kontroll; elmotor;

    Abstract : An optimization of a servo system for a satellite antenna system wasperformed. A brushless DC motor with an angle encoder was used, whoseangular velocity had to be controlled with great precision. Specializedhardware was used to implement field oriented control to directlycontrol the torque and magnetic flux of the motor. READ MORE

  5. 4. Torque-Based Load Estimation for Passenger Vehicles

    University essay from Linköpings universitet/Reglerteknik
