摘　　要：基于锁相环原理和基准脉冲技术，应用锁相伺服同步系统，实现了直接式位置跟踪控制，它把机床的齿轮传动链变成电子传动链，大大提高了系统的跟踪控制性能和柔性。Based-on phase-locked loops principle and reference-pulse technique,the phase-locked servo synchronism system is used and the direct model position tracking control is realized.Resultly the original gear drive chain is replaced by electronic drive chain,this can improve following control performance and its flexibility greatly,also this systim is successfully used in CNC gear grinding machine.
