Abstract: The Switched Reluctance Motor SRM is simple low cost faulttolerant newlinehas simple converter and control requirements Also SRM is fairly newlinesafe because of its characteristics of high tolerance robustness and possible newlineoperation in high temperatures or in intense temperature variations Hence newlinethis motor is suitable for many variable speed and servotype applications and newlineis gaining increasing attention in the motor drive industry However the newlineproblems of torque ripple and acoustic noise are more severe than those of newlineother traditional motors newlineThe causes of the torque ripple include the geometric structure newlineincluding double saliency excitation windings concentrated around the stator newlinepoles the working modes which are necessary for magnetic saturation in newlineorder to maximize the torque per mass ratio and pulsed magnetic field newlineobtained by feeding successively the different stator windings The phase newlinecurrent commutation is also the main cause of the torque ripple newlineVarious techniques have been proposed for torque ripple newlineminimization of SRMs Methods such as current profiling overlapping newlineconduction of different phases and linearized feedback control were used newlineMethods that use current profiling may produce high current peaks at low newlineregions Also most methods are highly dependent upon the rotor position newlineAny errors in the rotor position can lead to failure of the control Furthermore newlinemost methods are limited to lowspeed operation Hence the torque ripple can newlinebe minimized through magnetic circuit design in a motor design stage or by newlineusing torque control techniques newlineBy suitably controlling the torque of the SRM low torque ripple newlinenoise reduction or even increasing of the efficiency can be achieved There newlineare many different types of control strategy from simple methods to newlinecomplicated methods In this work motor design factors are not considered newlineand detailed characteristics of each control method are introduced in order to newlinegive the advanced knowledge about torque control method in SRM drive newline newline
