中文摘要:通过对开关磁阻电机转矩输出特性的研究,提出一种电流斩波控制与瞬时直接转矩控制相结合的改进型SRM转矩脉动抑制算法。采用CCC可设定SRM最大相电流值并增大换相重叠角,减缓转矩下降速度,简化转矩分配算法。本文搭建了SRM的 Matlab/Simulink改进型DITC转矩脉动抑制仿真平台。结果表明在简化换相重叠角转矩给定算法的同时可使SRM在安全允许范围内达到最佳转矩脉动抑制效果,具有实际应用价值。 |

Abstract:Through the research on the output characteristics of switched reluctance motor torque, a kind of improved direct instantaneous torque control was proposed, which combined chopped current control algorithm and DITC algorithm. By using the CCC algorithm, phase current of SRM was limited, the overlap angle was increased, the falling speed of torque was slowed, and the torque distribution algorithm was simplified. An improved DITC torque ripple rejection simulation platform was built by Matlab/Simulink software. The simulation results show that torque given algorithm in overlap angle is simplified and the best effect of torque ripple minimization of SRM in the security of the allowed range is achieved, which has practical application value. |
