英文摘要: Switched reluctance motor (SRM) has many excellent qualities, so how to restrain the torque ripple to make it more widely used and popularized has become a hot issue in academia. Although the traditional direct torque control (DTC) of switched reluctance motor can restrain the torque ripple to some extent, its restraining effect is limited. And also, there are problems such as big overshoot and weak robustness. In this paper, a direct torque controller based on Super-Twisting sliding mode control is designed. In addition, some improvements have been made to the direct torque controller. Finally, the theory was simulated and verified by using MATLAB/Simulink. The results show that, compared with the traditional direct torque control, the direct torque control of the switched reluctance...
中文摘要: 因为开关磁阻电机(SRM)具有很多优良品质,所以如何抑制它的转矩抖振使其能够得到更广泛的应用与推广成了学界的热点问题。传统的开关磁阻电机直接转矩控制(DTC)虽然能在一定程度上抑制电磁转矩脉动,但其抑制效果有限并存在超调过大、鲁棒性较差等问题。对此本文设计了一种基于Super-twisting滑模控制的直接转矩控制器,此外对直接转矩控制器也进行了一定的改进,最后利用MATLAB/Simulink 进行建模仿真分析。结果表明,与传统直接转矩控制相比,基于滑模控制策略的开关磁阻电机改进直接转矩控制系统有效地改善了系统的控制性能,使电磁转矩脉动更小,满足了控制需求。
