摘　　要：以直线伺服电机的冲击振动故障现象为研究对象,分析了混联结构下的直线伺服电机运动控制原理,从运动控制的角度解释了电机振动的原因。并提出了基于Turbo PMAC控制卡中预见控制功能的电机冲击振动抑制策略。通过实验证明,此振动抑制方案可以较好地抑制电机的冲击与振动,从而提高系统的控制性能。By considering the failure phenomena of the impact and vibration of linear servo motor as the study object, the movement control principle of the linear servo motor was analyzed, as well as explained the causes of the vibration in viewing of movement control based on the hybrid structure. The vibration suppression method on the impact and vibration of linear motor was given, which based on the preview-control function form Turbo PMAC. It is confirmed by experiment that the impact and vibration are well reduced which accounted for the application of this vibration suppression method, and the performance of the control system is improved.
