This article primarily introduces the structure of switched reluctance drive ( srd ) system and its development at home and abroad . the characteristic of switched reluctance motor ( srm ) and its electro - magnetics principle were described in details . the variation of srm winding current in different stage and the formula of toque and power were also analyzed in it 本文首先介绍了开关磁阻电机调速系统( srd )的构成及其在国际国内的发展状况，并对开关磁阻电动机的特点和电磁原理进行了阐述，分析了其绕组电流在不同阶段的变化情况以及转矩、功率公式。
On the basis of the analysis of srm torque model , a new control strategy is presented which solves the torque smooth transition in the process of commutation , thus reducing toque - ripple effectively . an online control scheme of the strategy is discussed in detail . the reduction of torque - ripple decreases the noise of motor effectively 在分析srm转矩模型的基础上，提出了一种控制策略用于解决换相过程中转矩平滑过渡的问题，从而有效地降低了转矩脉动，详细讨论了该控制策略的一种在线控制方案，转矩脉动的降低有效地降低了电机的噪声。
Bloom because it didn t suit you one quarter as well as the other ducky little tammy toque with the bird of paradise wing in it that i admired on you and you honestly looked just too fetching in it though it was a pity to kill it , you cruel creature , little mite of a thing with a heart the size of a fullstop 比起另外那顶插上极乐鸟翅膀的可爱的宽顶无檐小圆帽来，它连四分之一也跟你般配不上。你戴上那一顶，简直太迷人啦，我十分神往。可惜宰那只乌儿大损了，你这淘气残忍的人儿。
