6. An Isolated Integrated Charger for Electric or Plug-in Hybrid Vehicles
Abstract : For electric and hybrid vehicles using grid power to charge the battery, traction circuit components are not normally engaged during the charging time, so there is a possibility to use them in the charger circuit to have an on-board integrated charger.In this Licentiate thesis, an isolated high power integrated charger is proposed, designed and constructed based on a special ac machine with a double set of stator windings called motor/generator.

7. Grid-Connected Voltage Source Converter - Control Principles and Wind Energy Applications
Abstract : The thesis focuses on a forced-commutated voltage source converter (VSC) connected to a grid in a wind energy application. The work consists of four parts. The first part addresses the type of electrical system which should be used in a wind turbine. READ MORE

8. Network Synchronization and Control Based on Inverse Optimality : A Study of Inverter-Based Power Generation
Abstract : This thesis dwells upon the synthesis of system-theoretical tools to understand and control the behavior of nonlinear networked systems. This work is at the crossroads of three topics: synchronization in coupled high-order oscillators, inverse optimal control and the application of inverter-based power systems. READ MORE

9. Autonomic Management of Partitioners for SAMR Grid Hierarchies
Abstract : Parallel structured adaptive mesh refinement methods decrease the execution time and memory usage of partial differential equation solvers by adaptively assigning computational resources to regions with large solution errors. These methods result in a dynamic grid hierarchy. READ MORE

10. Fundamental Limitations of Distributed Feedback Control in Large-Scale Networks
Abstract : Networked systems accomplish global behaviors through local feedback interactions. The purpose of a distributed control design is to select interaction rules and control protocols that achieve desired global control objectives. READ MORE
