1. Wireless Control of Modular Multilevel Converter Submodules
Sammanfattning : The modular multilevel converter (MMC) has extensively been used in high-voltage, high-power applications such as high-voltage dc transmission systems and flexible alternating current transmission systems. The control of MMC submodules is conventionally realized using wired communication systems. LÄS MER
2. Control Aspects of Complex Hydromechanical Transmissions : with a Focus on Displacement Control
Sammanfattning : This thesis deals with control aspects of complex hydromechanical transmissions. The overall purpose is to increase the knowledge of important aspects to consider during the development of hydromechanical transmissions to ensure transmission functionality. LÄS MER
3. Power angle control of grid-connected voltage source converter in a wind energy application
Sammanfattning : .... LÄS MER
4. Industry applications of multivariable control
Sammanfattning : In the face of environmental regulations, optimization of industrial processes becomes necessary. This doctoral thesis summarizes the results of three application-driven projects in automatic control that were aimed at process optimization in the steel industry. LÄS MER
5. Dynamic Analysis of Harmonics in Electrical Systems
Sammanfattning : Frequency domain analysis and design of power systems is complicated in the presence of harmonics, switching dynamics, nonlinearities, unbalances, and for systems with mixed ac/dc dynamics. The reason is that linearization of the system does not lead to a time invariant system, but a system with periodically time varying dynamics, which implies that there is coupling between different frequencies.
