  1. 21. Near Field millimeter Wave Antenna Measurements

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Bharath Manjunatha; [2023]
    Keywords : Antenna Pattern; Near field to far field; Planar Scanning; Probe Compensation; Active Antenna; Technology and Engineering;

    Abstract : In the real world, understanding an antenna's radiation pattern is crucial for its proper utilization. Typically, antennas are tested in the far-field region, where the radiation lobes are fully developed and phase errors are less than pi/8. READ MORE

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

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

    Author : Xingyu Zhao; [2023]
    Keywords : 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.;

    Abstract : 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. READ MORE

  3. 23. Vibration Avoidance Based on Model-Based Control Incorporating Input Shaping

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Chenqi Ma; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 24. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Albin Lindvall; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.

  5. 25. Adaptive Rolling Radius Estimation

    University essay from Linköpings universitet/Fordonssystem

    Author : Rickard Wretlind; William Wärn; [2023]
    Keywords : Rolling Radius; Estimation; Rolling Radius Estimation; Tire; Tires;

    Abstract : Tire tread health is essential for safe operation of a passenger vehicle. Worn out tires significantly increases the risk of traffic accidents and hydroplaning. This thesis investigates the possibility to detect tire tread wear by estimating the effective rolling radius of a tire. READ MORE
