“…The current waveform profile has the name of torque sharing functions in literature, and in most cases it is generated by the use of sine or exponential waves with the rotor position as input, as seen, for example, in [11,15,16]. Another solution is the use of look-up tables which are much easier to change and give the right values in the right vector position.…”

The switched reluctance motor has been gaining interest both at the academic and industrial levels. Its most appreciated characteristics are the nonuse of rare elements and the low construction price. The control of the switched reluctance motor is not as easy as other traditional machines. In the control, it is necessary to reduce the torque ripple as much as possible, which has been the most studied problem in the field. This chapter aims to give the reader a concise but focused knowledge on how the switched reluctance motor can be controlled. Fundamental control methods and their impact in the motor performance are described. A simulation section is presented, where the simulation files are provided for the reader. The simulations are based on the theory described and have the advantage of using a non-linear switched reluctance motor model from a real motor.

“…These all require complex control [17], [18], accurate torque and rotor position measurement [19] and complex current regulation techniques [20]. Current profiling [21], [22] and torque sharing [23], [24], methods are just two solutions that can be used for minimizing the SRM torque ripples.…”

Abstract-The electrical drive systems used in automotive applications has to be both reliable and of high performance. To fulfill these demanding requirements a modular fault tolerant switched reluctance motor is proposed, which is controlled by means of an effective direct instantaneous torque controller. In the paper both the motor and the control system are described. By simulations the working principle of the drive system is illustrated and its performances are demonstrated.

“…In [19], a neuro-fuzzy compensator is used to shape the motor current by adding a compensating signal to the output of the controller. A modified TSF is presented in [20] where the incoming torque phase has been compensated by the outgoing phase while the supplemental outgoing torque phase has reduced the reference torque of the incoming phase. A unified control for minimizing torque ripple in SRM is proposed in [21], where direct instantaneous torque control and current control are implemented.…”

The torque ripple produced in a switched reluctance motor (SRM) can be seen as one of its major drawbacks. It occurs mainly due to the sequential switching of the motor phases and changes in the length of the air gap. The torque sharing functions (TSFs) are the more effective and favorable techniques developed to reduce the torque ripple in SRMs. However, the time responses of instantaneous torque for incoming and outgoing phases during commutation period (CP) are different. In addition, with increasing motor speed the CP decreases and the torque response of the outgoing phase oversteps it. In this paper, a modified torque sharing function based on the change of the overlap angle during the commutation process depending on the motor speed is presented. In the designed control algorithm of the TSFs, the motor speed is has become an input besides the rotor position and the torque command. The commutation time is precisely adjusted enough for the commutating process. The proposed method gives good results in a wide speed range. To deduce the magnetic characteristics of the SRM, finite element analysis (FEA) is applied and a look-up table model is derived. The effectiveness and robustness of the proposed control technique are exhibited in the simulation results.
