摘　　要：设计一个运动控制卡插补器。该运动控制卡是以DSP和CPLD为核心的位置控制系统,插补器包含两级插补:粗插补部分采用时间分割法插补,由DSP实现,针对时间分割法存在的问题对其算法进行了改进;精插补部分采用DDA插补法,由CPLD实现。A motion control card interpolator was designed.The motion control card based on DSP and CPLD was a core position control system.The interpolator contained two level interpolations.The coarse interpolation using time division interpolation method, was implemented by DSP.In view of the problems existing in time division method,the algorithm was improved.The fine interpolation was realized by CPLD,in which DDA interpolation method was adopted.

关 键 词：插补器 运动控制 时间分割法插补 DDA插补法
