摘　　要：超精密数控车床加工精度的提高不仅依赖于数控装置的运算速度和曲线的拟合精度，同时还依赖于伺服系统的跟踪精度和点位控制精度。现主要讨论一种采用双频激光干涉仪作为位置反馈元件的基于POPOV超稳定性理论的自适应微动控制器的设计和实验过程。实验结果表明，采用本伺服控制系统可以使超精密机床的定位精度提高到纳米级。The manufacture precision of super exactitude NC lathe depends on not only the operation rate of NC deviceand joined precision, but also the error of track and point location about servo system. The paper discusses how to designand test the micro self - adjustable controller with double frequency laser intervener and theory of super stability based onPOPOV. The servocontrol system has the position precisionjust as nanometre.
