  1. 26. Online Parameter Estimation of a Six- Phase Machine for Marine Application

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Raimundo Montalba Mesa; [2021]
    Keywords : Multiphase electrical machines; IPSM; Parameter estimation; Online estimation; Stator resistance estimation; Permanent magnet flux estimation.; Flerfas elektriska maskiner; IPSM; Parameteruppskattning; Online uppskattning; Statorresistans uppskattning; Flödesuppskattning av permanentmagneter.;

    Abstract : In the recent decades, an increased interest into multiphase machines has developed due to certain beneficial properties they have over the standard three- phase machines. Proper modelling of a multiphase machine allows access to higher degrees of freedom given by the ability to control higher order harmonic frames. READ MORE

  4. 28. 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

  5. 29. Analysis of Different Switching Patterns to Minimize Losses in a Six- Phase Drive for Marine Application

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yanick Patrick Frei; [2021]
    Keywords : Multiphase machines; Switching patterns; Winding conduction losses; Converter losses; MATLAB SIMULINK; Flerfasmaskiner; Modulatorer; Spolledningsförluster; Omvandlarförluster; MATLAB SIMULINK;

    Abstract : Multiphase machines have gained a lot of popularity during the recent years, as they offer certain benefits over their three- phase counterparts. This work investigates the losses of a six- phase drive system for a marine application when supplied by four different switching patterns (also referred to as modulators). READ MORE

  6. 30. Comparison of high density and bipolar surface EMG for ankle joint kinetics using machine learning

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Federica Aresu; [2021]
    Keywords : EMG; HD-sEMG; machine learning; joint torque;

    Abstract : The relationship between sEMG signals and muscle force, and associated joint torque, is an object of study for clinical applications such as rehabilitation robotics and commercial applications as wearable motion control devices. The information type and quality obtained by sEMG can impact the classification and prediction accuracy of ankle joint torque. READ MORE
