爬行

The relationship between system parameter and low-speed slip-stick phenomenon is found, and the condition of choosing the parameter of PID is given, which should satisfy the purpose of overcoming low-speed stick-slip and guaranteeing the stability.

通过该判定定理得到系统参数与低速滞滑爬行的关系，在满足常规稳定控制器参数选择范围的基础上，给出了为消除低速滞滑爬行，PID控制器参数还应满足的条件。

And the motion simulation for the creeping is made in the virtual simulation software ADAMS. By the result analysis and contrast, it can get the ideal purpose with the ADAMS to analyze directly.

并在虚拟仿真软件ADAMS12.0中进行机床爬行的运动仿真，从结果分析比较，直接用ADAMS进行爬行现象分析，能得到理想的效果。

Creeping wave is a sort of key problems of the non? mirror surface scattering.

爬行波是非 镜面 散射问题中的一类重要问题,射线寻迹是求解爬行波散射贡献的关键环节.
