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)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. Vibration Avoidance Based on Model-Based Control Incorporating Input Shaping
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)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
3. Adaptive Trajectory Tracking Control of a UAV using Gaussian Processes
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Unmanned aerial vehicles are a popular choice for various transport and monitoringapplications. In many outdoor applications frequent variations of thevehicle conguration and time-varying disturbances originating from the environmentare expected. LÄS MER
4. Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. Modeling and Compensation of Nonlinear Distortion in High Efficient Electrodynamic Loudspeakers
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Signaler och systemSammanfattning : 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
