Examples
- Test methods for fiber optic test sources
光学纤维试验光源的试验方法 - During running , computer deal with fuzzy rules and carry out the best adjust of pid parameters . we programmed with modularization idea of labview , we achieved to set the test parameter , data acquisition , data processing and result display , communication with the optic testing instrument . we also achieved to drive no - ni daq and efficiency the system software by use multitasks
设计中通过对ld和pd的电流进行采样构成acc和apc两种电流控制方式对ld驱动电流进行闭环控制;采用参数模糊自整定pid控制算法,实现对温度的控制,在线运行过程中,计算机对模糊规则结果处理、查表和运算,完成对pid参数的最佳调整。 - An optimizing arithmetic for calculating the best - fit sphere is also proposed , the result shows better accuracy is reached comparing to " three points method " , from 107 . 8umrms to 25 . 66umrms . during interferometric optics test with null lens , " nonlinear errors " of the testing coordinates will be introduced . a method based on ray - tracing , nonlinear fitting and coordinate transferring is proposed to eliminate these errors
在ccos控制模型及理论计算方面，提出了一种适用于高次离轴非球面最接近球面计算的优化算法，经计算，某矩形离轴非球面最接近球面半径的求解精度较传统的“三点法”有了较大的提高，理论加工余量由原来的107 . 8umrms降低到25 . 66umrms ；提出一种基于磨头与工件的相对位移量的控制模型，并且开发了阻尼卷积迭代算法，引入“虚拟加工”的概念进行迭代求解和参数评价。
