摘要
分析了五相混合步进电机电磁转矩波动产生的原理,提出了利用时变周期信号的重复控制来抑制转矩波动的新思路。首先将时变的t域的转矩信号,变换为具有固定周期的q域信号,再对其进行重复控制器设计,保持理想的驱动总电流,抑制转距波动。仿真与试验结果表明该控制方法效果明显。
Based on repetitive control of time-varying periodic signals, a new method of restraining toque ripple for 5-phase hybrid stepping motor system is proposed, and the principle of torque ripple is analyzed. The idea is to transform the time-varying periodic toque disturbance in t-domain to the signals defined in the q-domain and moreover to design a repetitive controller. The control scheme is applied to keep the total driving current ideality, so as to restrain the toque vibration. The simulation and experiment are presented to show the effectiveness of the new hybrid stepping motor system control scheme.
