| 在纺织行业的绣花机、针织横机应用中，为了改善步进电机开环控制系统下产生低频共振、高频失步和转矩下降的问题，课题组基于两相混合式步进电机的数学模型，利用三相空间矢量脉宽调制SVPWM推导了基于双H桥逆变电路两相SVPWM方法，并结合坐标变换、矢量控制和PI调节，在MATLAB/Simulink下搭建了一种新型两相混合式步进电机矢量控制系统模型。电流仿真结果显示电机在运行后0.3 s内电流达到稳定，速度仿真结果显示：电机低频运行转速在0.018 s时响应且稳定无振荡，高频运行时转速达到峰值后转矩稳定。课题组提出的方案能够提高两相混合式步进电机在振荡、失步方面的性能。 |

| In order to solve the problems of low frequency oscillation, high frequency step out and torque decline in the open loop control system of stepping motor used in embroidery machines and flat knitting machines in textile industry, a novel vector control system model of two phase hybrid stepping motor was established. Based on the two phase hybrid stepping motor (hybrid stepping motor, HBS) mathematical model, the three phase space vector pulse width modulation (SVPWM) was used to deduce the two phase SVPWM method based on the double H bridge inverter circuit. The coordinate transformation,vector control and PI regulation were also combined to build this novel model under MATLAB/Simulink. The current simulation results show that the current of the motor is stable at 0.3 s after operation. The speed simulation results show that the speed of the motor is stable and without oscillation at 0.018 s at low frequency operation, and the torque is stable after the speed reaches the peak at high frequency operation. Therefore, the scheme can improve the performance of two phase hybrid stepping motor oscillation and step out. |
