16. Planning and Control of Uncertain Cooperative Mobile Manipulator-Endowed Systems under Temporal Logic Tasks
Sammanfattning : Control and planning of multi-agent systems is an active and increasingly studied topic of research, with many practical applications such as rescue missions, security, surveillance, and transportation. This thesis addresses the planning and control of multi-agent systems under temporal logic tasks. LÄS MER
17. Performance Quantification of Interarea Oscillation Damping Using HVDC
Sammanfattning : With the transition towards renewable energy, and the deregulation of the electricity market, generation patterns and grid topology are changing. These changes increase the need for transfer capacity. One limiting factor, which sometimes leads to underutilization of the transmission grid, is interarea oscillations. LÄS MER
18. Decentralized Control of Networked Systems : Information Asymmetries and Limitations
Sammanfattning : Designing local controllers for networked systems is challenging, because in these systems each local controller can often access only part of the overall information on system parameters and sensor measurements. Traditional control design cannot be easily applied due to the unconventional information patterns, communication network imperfections, and design procedure complexities. LÄS MER
19. Frihet under kontroll : Om kontroll i åkerinäringen
Sammanfattning : This dissertation, based on two studies, examines the significance of formal control, i.e. the actors and agencies whose formal task involves the use of a range of measures to exercise control within the road haulage industry. LÄS MER
20. Voltage sag ride-through of AC drives : control and analysis
Sammanfattning : This thesis focuses on controller design and analysis for induction motor (IM) drives, flux control for electrically excited synchronous motors with damper windings (EESMs), and to enhance voltage sag ride-through ability and analysis for a wind turbine application with a full-power grid-connected active rectifier. The goal is to be able to use the existing equipment, without altering the hardware. LÄS MER
