The friction drive mechanism moves well even when driven at high frequency and with long strokes, so it can be used with open-loop control systems for micro displacement.
进给速度可通过改变驱动脉冲的频率调节，机构在高频驱动大位移动作时亦表现出准确的步进特性，可用于小型机电系统的开环进给驱动。
The precision of this mechanism is checked by open-loop control and closed-loop control.
采取开环控制和闭环控制两种方式检验了该机构的精度，并讨论了误差产生的原因。
