Open publisher page 13 citations

Abstract

In this paper, a novel methodology for control of torque and flux of switched reluctance motor (SRM) drive in a hystersis manner is described. The philosophy of control is the direct torque control (DTC) by analysis the non-uniform torque characteristics of the motor. The scheme directly controls the torque and the torque ripple by controlling the magnitude of flux linkage and change in speed of stator flux vectors. Further importance is given to overcome the difficulties of conventional linear and non-linear controls of SRM drives. This new technique can be implemented in real time with low cost microcontrollers and higher simplicity.
