A new model reference adaptive system based estimation technique for vector control of real and reactive power a brushless doubly fed reluctance generator without shaft position sensor is proposed. The rotor speed being precisely observed in closed-loop manner by eliminating the error between measured estimated inverter-fed (secondary) winding current angles stationary frame. Contrary to existi...

In this work, we are interested in improving the performance of a doubly-fed induction generator (DFIG)-based wind system, by applying sliding mode control strategy. The objective is regulation active and reactive power, also voltage frequency signal injected into distribution network. model proposed for based on technique with estimators. was validated simulation MATLAB/Simulink.

Nested-loop secondary linear doubly-fed machine (NLS-LDFM) is a novel evolved from rotary brushless induction machine, which has good application prospect in metro. In order to analyze the performance of NLS-LDFM, mechanism and action rules end effects are investigated this paper. Firstly, static dynamic analyzed aspect direct coupling, winding asymmetry transient current. Furthermore, based on...
