| 目的 研究不同工况下包装机生产线中异步电机控制算法的在线灵活切换。方法 选用2种异步电机高性能控制策略FOC和DTC作为包装机电机算法的切换对象，研究2种算法的共同基础，得出新的FOC_DTC算法作为切换系统的过渡算法，有效解决2种控制策略在线相互切换带来的转矩、电流突变等问题，并且在硬件平台上与直接切换方案、重置PI切换方案进行对比。结果 在满足包装机各个工况要求的前提下，混合FOC_DTC切换系统在切换响应时间、切换平滑度和切换效率上比上述2种方案更优越，切换响应时间提高了2%，切换转矩尖峰降低了30%。结论 通过使用混合FOC_DTC切换系统，包装机在不同工况下可以在线实时切换动力系统电机的控制算法，在平滑度和响应时间上比其他方案有明显的优势。 |

| The paper aims to study the online free switching of asynchronous motor control algorithm of packaging machine production line under different working conditions. Two high-performance control strategies FOC and DTC were selected as the switching object of the asynchronous motor algorithm of the packaging machine, and the common basis of the two algorithms was studied. A new FOC_DTC Algorithm was obtained as the transition algorithm of the switching system, which effectively solved the torque and current glitch caused by the online switching of the two control strategies. Furthermore, based on the hardware platform, the direct switching scheme and the reset PI switching scheme were compared with the proposed scheme. On the condition of meeting the requirements of all working conditions of the packaging machine, the hybrid FOC_DTC switching system had advantages over the above two schemes in switching response time, switching smoothness and switching efficiency, which improved the switching response time by 2% and reduced the switching torque peak by 30%. By using the hybrid FOC_DTC switching system, the packaging machine can switch the control algorithm of the power system motor online and real-time under different working conditions, which has obvious advantages over other schemes in smoothness and response time. |
