Bassirou Sock, Digital controller using dynamic pole placement by polynomial approach for power factor correction circuit, M. For controlling stator active and reactive power of DFIG connected to the grid, a state feedback controller for the DFIG has been developed using a linear quadratic optimal theory with preview concept.
Surrogate models of the machine are constructed using Latin Hypercube sampling and the Kriging modelling. These terms are shown to relate directly to the design of the rotor, and are quantified using the previously developed framework. Wind energy is the fastest growing renewable energy source and is making a significant contribution to meeting the energy demands while still reducing CO2 emissions.

Show full item record Citation Roberts, P. In literature, number of controllers such as conventional proportional integral PI control, linear parameter varying LPV control, gain scheduling control, robust control, model predictive control have been proposed for both torque and pitch control. The experimental method is shown to be applicable both to standard induction machines and to BDFM machines, yielding accurate results in each case.
The coherence between the different models allows parameters calculated for the coupled circuit model to provide parameter values for the other models. Thesis, Sharif University of technology, winter 7. This dissertation contributes towards this goal through machine analysis, design and control.
The original machine is then rewound following the optimised plan and tested to determine the difference in performance. An initial attempt at implementation of the scheme is reported.
This Optimal preview control is used to solve the tracking and rejection problems with an assumption that the signals to be tracked or rejected are available a priori by a certain amount of time. As the number of installed wind turbines increases across the world, questions of turbine component failure and repair are also receiving much attention.

PhD thesis. an abstract of a thesis modeling, control and analysis of a doubly fed induction generator based wind turbine system with voltage regulation. This thesis focuses on the analysis of fault conditions and investigates effective fault ride-through and protection schemes in the electrical systems of wind farms, for both small-scale land and large-scale offshore systems.
