摘要
与传统的交直流电动机相比,开关磁阻电动机(Switched Reluctance Motor,简称SRM)的主要缺点是其转矩脉动较大以及由此引起的噪声和振动。通过引入直接瞬时转矩控制(Direct Instantaneous Torque Control,简称DITC),可有效减小SRM控制系统的转矩脉动。介绍了SRM-DITC可逆运行系统的主要组成,并提出了在可逆运行工作模式下的DITC方法。通过仿真和DSP物理实验,验证了所提方法的有效性。
Compared with the conventional AC/DC motor,the torque ripple is a primary disadvantage for the switched reluctance motor （SRM）.On the basis of direct instantaneous torque control （DITC）, the torque ripple of SRM can be reduced.As a high performance adjust speed system, SRM should have reversible drive ability.The new methods for reversible drive system of SRM are presented.The composing of reversible drive system of SRM based on DITC is introduced.The validity of proposed method is verified by the computer simulation and experiments.
