While working at dynamic state  original outputs of the photoelectric encoder are in theory two sine or triangular signals with a phase difference of /2. However  there are still deviations of actual output signals. Interpolating on the basis of this deviation signal will result in interpolation errors. In dynamic state  true original signal data obtained by data acquisition system is a time equation. Through processing these data by data equiangular and harmonic analysis  the equation will be converted from time domain to position domain and an original position equation can be formed. Then the interpolation errors also can be obtained. By this method  the interpolation errors can be checked in dynamic state and it can also provide electric interpolation basis so that to improve dynamic interpolation precision of the encoder. Software simulation and experimental analysis all prove the method effective. This method is he basis in theory for precision checking and calibration in motion. 2009 SPIE.   generation of finite element mesh with variable size over an unbounded 2d domain 期刊论文  OAI收割 COMPUTER METHODS IN APPLIED MECHANICS AND ENGINEERING, 2005, 卷号: 194, 期号: 45-47, 页码: 4668-4684 Lo SH; Wang WX   |  收藏  |  浏览/下载：25/0  |  提交时间：2011/07/28 unbounded domain  triangular mesh generation  advancing front  circle packing  neighbour tracing  boundary recovery   orthogonal piece-wise polynomials basis on an arbitrary triangular domain and its applications 期刊论文  OAI收割 JOURNAL OF COMPUTATIONAL MATHEMATICS, 2001, 卷号: 19, 期号: 1, 页码: 55-66 Sun JC   |  收藏  |  浏览/下载：8/0  |  提交时间：2011/07/29 orthogonal piece-wise polynomials  triangular domain  eigen-decomposition
