This will arise ripple in the control system speed response. Speed filtering can decrease the ripple  but it's not good enough  and it also induces lag. A speed feedback method based on all-state observer was introduced to improve the speed feedback performance. Experiment results show that  compared to filtering method  the control system performance is improved.   The deviation of color matching algorithm in the field of full-color LED display (EI CONFERENCE) 会议论文  OAI收割 2009 2nd International Congress on Image and Signal Processing, CISP'09, October 17, 2009 - October 19, 2009, Tianjin, China 作者:  Wang Y.;  Chen Y.;  Zhang X.;  Zhang X. 收藏  |  浏览/下载：19/0  |  提交时间：2013/03/25 In this paper  a color gamut transformation method which transformed the different color gamut into a same one has been proposed. In the transforming process  the deviation which was arose from the quantization error and the truncation error were existing. If the deviation was out of the color tolerance  the uniformity of the screen color will be deteriorated. Firstly  the color tolerance of vision was calculated by the color-difference formula. Secondly  in the full-color LED display experiments  it was analyzed that the tri -color tolerance values are respectively 2.5  2.8 and 1.3. According to the tri -color tolerance values and the color difference formula  the express of the quantization precision  gray value and the color difference was set up. Finally the gray-scale range of the color uniformity was analyzed by the collected data  it was concluded that the uniformity of the display was satisfied the requirement of the visual when the range of the gray level was [11  14]  and when the range was [1  11]  the value of the color difference was also reduced significantly. 2009 IEEE.   Discrete Laplace-Beltrami operator on sphere and optimal spherical triangulations 期刊论文  OAI收割 INTERNATIONAL JOURNAL OF COMPUTATIONAL GEOMETRY & APPLICATIONS, 2006, 卷号: 16, 期号: 1, 页码: 75-93 作者:  Xu, GL   |  收藏  |  浏览/下载：17/0  |  提交时间：2018/07/30 Laplace-Beltrami operator  convergence  spherical triangulation  truncation error   A note on the truncation error for the ge scheme 期刊论文  iSwitch采集 International journal of computer mathematics, 2002, 卷号: 79, 期号: 9, 页码: 1009-1012 作者:  Zhang, BL;  Wan, ZS;  Evans, DJ 收藏  |  浏览/下载：55/0  |  提交时间：2019/05/09 Ge scheme  Truncation error  Diffusion equation
