ABSTRACT A classical direct torque control (DTC) of switched reluctance motors (SRMs), multiple switch state combinations should be traversed; this may lead to complex calculations. To solve this problem, a two‐level hysteresis torque band‐based DTC for SRM with switching states restructuration is proposed. The two factors maximize the strategy: In order to address the issues of torque, oscillations brought on by the gradual drop in terminal current, and the fact that the actual torque cannot instantly track the reference torque in the initial excitation region of the incoming phase, a 16‐sector switch state allocation method is first used. However, by optimizing the switch state combination rules through partitioning, the number of candidate switch state combinations is significantly reduced to four. Additionally, a sector reorganization algorithm based on voltage vectors (VVs) is integrated into the proposed DTC scheme. This algorithm enhances torque compensation by selecting the phase with superior torque tracking capability and dynamically adjusting the allocation of compensation modes through real‐time position updates. The experimental results demonstrate that the proposed DTC approach effectively reduces computational burden while achieving superior torque ripple suppression compared to conventional control techniques.
