In this article, a generalized sensorless method for SRM drives has been explained. By continuous monitoring of the back-EMF, the best version of the sensorless technique is selected and engaged. The robust performance obtained from this technique makes it as attractive candidate for industrial as well as domestic applications. Furthermore, a four-quadrant strategy under sensorless control has been designed and implemented. The proposed method demonstrates simplicity in computation while providing high-precision position information with no extra hardware or memory. The proposed algorithms have been implemented on an experimental SRM test setup. Our findings show that four-quadrant sensorless control of the SRM drive is a feasible technique and can be considered as a technology ready for application. This technique is especially helpful where the characteristics of the application calls for operating in two/four-quadrants or when a closed-loop speed/position control with sensorless strategy is demanded.
