  1. 1. Enhancing Servo System Performance : Robust Nonlinear Deadbeat Predictive Current Control for Permanent Magnet Synchronous Motors

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Xingyu Zhao; [2023]
    Nyckelord :keywords here: Deadbeat Predictive Current Control; Permanent Magnet Synchronous Motor; Flux Linkage Nonlinearity; Parameter Inaccuracies; Nonlinear Feedforward Compensation; Delayed Integral Action.; Deadbeat-prediktiv strömreglerin; Permanenta magnet-synkronmotorn; Ickelinjäriteter i flödeslänkningen; Felaktigheter i parametrar; Icke-linjär framåtmatningskompensation; Fördröjd integralåtgärd.;

    Sammanfattning : The Permanent Magnet Synchronous Motor (PMSM, also known as the servo motor) is a crucial component within robotic servo systems. To optimally respond to the torque demands sent from the high-level motion controller, the PMSM current controller must track the reference with speed and precision. LÄS MER

  4. 4. Consequences of Nordic Conditions on the Performance of Large-Scale Building Applied PV Installations

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Ali Kurdia; [2017]
    Nyckelord :Solar; PVsyst; Nordic; meteorological; solar systems; PV; photovoltaic;

    Sammanfattning : This thesis aimed for a better understanding of the Nordic weather conditions in terms of snow induced soiling on the performance and production of an established photovoltaic plant located on the roof of Økern nursing home, Oslo. In order to realize the main aim, several steps had to be done in preparation of the main analysis, these steps in fact are as important to this thesis as the main deliverable. LÄS MER

  5. 5. Optimization of intermediate storage size in a production process subjected to Variable customer demands for an efficient material Utilization. : A case study on the production process at SKF

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Samuel Godians; [2014]
    Nyckelord :Production processes; Optimizing Storage system; Production Cycle time; Operation;

    Sammanfattning : Intermediate storage system optimization is an essential aspect which this report tends to look upon and putting effort on improving operating efficiency then reducing the capital cost of batch/ semi-continuous or flow production process by looking at the extent of estimating the figures of boxes that are made to be in the intermediate storage system through evaluations. Additionally, intermediate storage can reduce the effects of process parameter variations, such as recipe inaccuracies and operator errors, in which process operations are particularly visible.
