“…The electrical machine is current-controlled by means of a hysteresis band strategy. Other usual alternatives are closed-loop pulse-width-modulation (PWM) [39] and direct torque control (DTC) [40]. Motor mode operation requires the use of +U DC and 0 V to keep the current within the reference band, using − U DC to switch the current off rapidly when the phase is deactivated, as Figure 7 illustrates.…”

There are many types of electrical machines suitable for electric vehicles. Nowadays, most manufacturers and researchers tend towards two major alternatives: permanent magnet synchronous machines and induction machines. However, these are not the only competitive candidates. Reluctance machines, which have been well-known for some decades already, present some interesting advantages. For instance, switched reluctance machines are intrinsically redundant and fault-tolerant, which makes them attractive for applications in which robustness is compulsory. In this sense, switched reluctance drives can keep working even when one of their phases loses its functionality for any reason. In an electric vehicle, this would mean being able to keep driving the vehicle even after some failures, although with reduced performance (in degraded mode). In this chapter, switched reluctance drives for traction applications are analyzed, focusing on their capability to operate in degraded mode (with m-1 phases available).

“…Currently, two widely employed strategies for achieving smooth torque control in SRMs are direct instantaneous torque control (DITC) and direct torque control (DTC). The mechanism of DTC is intricate as it involves individual control of torque for each phase [7,8].…”

The rising demand for clean and abundant energy sources has guided growing interest in transportation electrification. Recently, a broad interest in electric vehicles (EVs) and their development has begun due to oil depletion, price rise, and the air pollution produced by cars with internal combustion engines (ICE). Therefore, the researchers are motivated to seek alternative energy sources to propel the car. Nowadays, switched reluctance motor (SRM) is gaining more and more attention in recent high-speed industrial applications. The researcher's trend has moved towards developing more environmentally friendly systems. This study aims to improve the SRM drive system to achieve reliability and torque quality. It proposes a rapid optimization-based bacterial foraging procedure for selecting the optimum value commutation angles. Quality indicators like torque ripple measure motor performance in terms of acoustic noise and mechanical vibration. The percentage of torque ripple is employed as a metric to assess the quality of SRM drive torque. The results indicate that minimizing torque fluctuations in an SRM motor is feasible by selecting an appropriate commutation angle through optimization.
