Abstract
A sensorless speed control technique for brushless doubly-fed reluctance machine (BDFRM) drive using fictitious quantity (X = v∗ s × i s ) based model reference adaptive system (MRAS) is proposed in the present work which is suitable for pump storage and wind power generation applications. The proposed MRAS (X-MRAS) shows stable operation in all the four quadrants of BDFRM drive. In this context, the performance analysis of the complete BDFRM drive, is done under maximum torque per inverter ampere (MTPIA) condition for both motoring and generating modes of operation using MATLAB/SIMULINK. A study on stability and sensitivity analysis of the complete drive system is also included to confirm the efficacy of the scheme.
