  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

  2. 2. Vibration Avoidance Based on Model-Based Control Incorporating Input Shaping

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Chenqi Ma; [2023]
    Nyckelord :Multi-joint industrial robot; Vibration avoidance; Path deviation; Input shaping; Extended flexible joint model; Nonlinear gray-box identification; Fleraxlade industrirobotar; Vibrationsdämpning; Banavvikelse; Ingångsformning; Utökad flexibel axelmodell; Icke-linjär gray-box modell;

    Sammanfattning : VIBRATION AVOIDANCE, a technique to proactively remove unwanted or excessive vibrations in multi-joint industrial robots, has shown to be desired in various applications. A trade-off between vibration avoidance performance and path deviation has been thekey criteria for assessing the effectiveness and quality of an approach. LÄS MER

  4. 4. Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Sergio Steven Gutierrez; [2020]
    Nyckelord :QAM; NLIN; NLPN; Machine Learning; Coherent Optical Communication; Nonlinear Noise Compensation; Physics and Astronomy; Technology and Engineering;

    Sammanfattning : In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. LÄS MER

  5. 5. Modeling and Compensation of Nonlinear Distortion in High Efficient Electrodynamic Loudspeakers

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Signaler och system

    Författare :Caroline Holmström; [2020]
    Nyckelord :;

    Sammanfattning : Loudspeakers transform electrical energy into acoustic waves but most of the electrical energy is lost as heat. It is possible to increase the electro-acoustic efficiency by changing the electrical, mechanical or acoustical design of the loudspeaker but with these changes come unwanted side effects. LÄS MER
