Electric drive without electrical and mechanical sensors is the critical obligation in most of the industrial applications due to its user-friendly hardware, lower maintenance, low cost, more reliability, etc. To replace the sensors, a number of schemes are employed, which extract the sensored data from the known parameters by using the machine model and/or its mechanical structure. In the past few years, researchers developed a variety of sensorless schemes for various applications by using different drives and their control algorithms to make it vigorous in any electrical, mechanical, and physical environments. In this paper, more than 275 publications were critically reviewed and the technological progression was presented for the sensorless control of electric drives by various motor control techniques. In addition to this, the review of sensorless AC drive system and its application was also studied and presented. [ABSTRACT FROM AUTHOR] |
