Analysis of Current Gradient Sensorless Method of Switched Reluctance Motor
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 7
Abstract
In the present work performance of current gradient sensorless method (CGSM) of switched reluctance motor is examined. Major issues of CGSM associated with design, implementation and performance are investigated. It covers detail analysis of current peak detection, rotor position estimation and commutation logic due to non linear inductance characteristics, effect of PWM frequency, use of low pass filter and phase-locked-loop (PLL). Suitability and limitation of the CGSM are discussed. Piece wise solutions are proposed with mathematical support for each problem. This paper explores untouched issues of the CGSM particularity for low frequency SRM drive.
