[en] A novel method, the simple reluctance-based efficiency control for the switched reluctance motor drives, is proposed in this paper. This concept is realized by programming the ratio of current command to phase voltage, and to utilize the time-dependent derivatives of equivalent magnetic inductance obtained from reluctance-related opinion. The algorithms and computational procedures are derived and completed taking equivalent magnetic inductance into consideration. Simulation and experimental results demonstrated the validity of the capability for efficiency regulation of the proposed method
