摘　　要：在张力控制收放卷工艺中,使用张力计闭环方案可以使最终成品质量提升,提高工厂运行效率。但使用张力计闭环方案时,对于变频器的转矩输出精度有相应的要求。施耐德变频器第五代电机控制算法(AEMC)改善了转矩输出精度及动态响应性能,在全速度范围内可以将输出转矩精度控制在4%以内。在无溶剂复合机收卷工艺实际应用中,使用集成了AEMC算法的ATV930系列变频器成功的解决了加速阶段出现的松膜及断膜问题。Use close-loop scheme with tensiometer can improve the quality and operation efficiency in the winding process of tension control applications.However,the close-loop scheme of tensiometer requires the torque accuracy of below some values.The fifth-generation motor control algorithm(AEMC)of Schneider drives improve the output torque accuracy and dynamic response performanee.The output torque accuracy below 1%in all speed range.In the practical application of winding process of solvent-free compound machine,ATV930 series drive with AEMC algorithm solve the problems of film loosening grid film breaking in the acceleration stage successfully.
