Doubly Fed

The performance of doubly fed induction generator (DFIG) based wind turbines supplying local isolated load is manly up to the stator-voltage control strategy. Compared with conventional steady mathematic model based one, a dynamic mathematic model based stator-voltage decoupling control strategy was proposed in the paper, by which the accuracy of stator voltage was improved greatly. In this paper, the dynamic mathematic model of stator voltage and then the proposed stator-voltage decoupling control were deduced, based on which the corresponding decoupling control strategy was designed and analyzed. At last, the stator-voltage decoupling control strategy for DFIG based wind turbine supplying local isolated load was achieved. To validate the design and analysis, the simulation model was built in the Matlab/Simulink environment, and some important results were reported in the paper.

The cotton recognition would become rather difficult during the application of the cotton harvesting robot (CHR) in the case where the cotton is sheltered or covered by other objects. In this paper, a novel approach of cotton detection based on the improved randomized Hough transform (IRHT) for this case is proposed. Based on the contour information from the boundary trace, the mathematic model-based IRHT is derived based on a modified circular detection technique. It yields a well agreement with the requirements of the precision and rating of CHR.
