closed loop

1.Virtual haptical system is a circulate feedback closed loop, including bidirectional information transfer between virtual and really environment.

虚拟触觉系统是一个触觉信息循环反馈的闭环系统,含着虚拟环境与现实环境两者之间双向的信息传递。

2.It has been proved that this method is fit for the parallel linable fringes and the interferograms with the arbitrary closed loop fringe pattern.

该方法具有度高、抗干扰的特点，不仅适用于平行直线型图像，而且对含闭的复杂干涉图像同样适用。

3.Main loop uses silicon-controlled hexaphase half-wave closed loop control technology, not influenced by electrical network voltage undulation and welding cable length, the performance is more stable.

主回路采用可控硅六相半波闭环控制技术，不受电网电压波动和焊接电缆长度的影响，性能更加稳定。
