In this paper present a sensorless maximum wind power extraction for variable speed constant frequency (VSCF) wind power generation systems with a doubly-fed induction generators (DFIG), to ensure stability and to impose the ideal feedback control solution despite of model uncertainties , using the principles of an active and reactive power controller (DPC) a robust sliding mode power control h...

The usual method for the construction of a wavelet basis in the Hilbert space L 2 (R) via a Multiresolution Analysis (MRA) does not necessarily succeed in a Banach space, although MRAs can be constructed easily, as e.g. L 1 (R) shows. We explain this phenomenon by considering sequences of projections rather than subspaces, and by studying which properties of projection operators can or can not ...

Nonsense-mediated mRA decay (NM) is an importt mRA surveilance mechanism conserved in eukaryotes. This thesis explores several interesting aspects of the NM pathway. One importnt aspect of NM which is presently the subject of intense controversy is the subcellular localization ofNM. In one set of experients, the decay kinetics of the ade2and pgkl nonsense mRAs (substrates for NM) were investiga...

Nonlinearity is the inherent characteristics of all the industrial processes. The Classical control approach used for a generation often fails to show better results particularly for non-linear systems and in the systems, whose parameters changes over a period of time for a variety of reasons. Alternatively, adaptive control strategies provide very good performance. The Model Reference Adaptive...

Observer based approaches are commonly embedded in sensorless variable speed drives for the purpose of speed control. It estimates system variables to produce errors or residual signals in conjunction with corresponding measurements. The residual signals then are relied to tune control parameters to maintain operational performance even if there are considerable disturbances such as noises and ...
