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.   Real time method for airport runway detection in aerial images (EI CONFERENCE) 会议论文  OAI收割 ICALIP 2008 - 2008 International Conference on Audio, Language and Image Processing, July 7, 2008 - July 9, 2008, Shanghai, China 作者:  Wang Y.;  Wang Y.;  Wang Y.;  Wang Y.;  Wang Y. 收藏  |  浏览/下载：42/0  |  提交时间：2013/03/25 In this paper  we propose a novel method that combines improved chain codes based edge tracking (ICCBET) with Hough transform (HT) to successfully detect the airport runway in real time. ICCBET primarily removes the short and curving lines to reduce the pixels and confirms the approximate orientation to shorten the angle range HTprocesses in later. Furthermore  through using pyramid during HT stage  the computation cost is reduced considerably to satisfy real time performance. Finally  we fix the memory by designing a chain list array for the image to avoid overflow arise from building chain list with memory dynamic allocation. Experiments on various images show that our method satisfies the real time need with about 23.5 multiples computation reduction contrast to the original Hough transform (OHT) and overcomes the blur to localize the lines with high accuracy contrast to the original chain codes based edge tracking (OCCBET). 2008 IEEE.   ON THE SLUG-ANNULAR TRANSITION OF TWO-PHASE GAS-LIQUID FLOWS AT MICROGRAVITY 会议论文  OAI收割 5th China-Japan Workshop on Microgravity Sciences, Dunhuang,Gansu Province, China, 2002-09-01 作者:  Zhao JF(赵建福);  Hu WR(胡文瑞) 收藏  |  浏览/下载：50/0  |  提交时间：2015/09/10 annular  perturbation  instability  accordance  continue  bubble  arise  assumption  matched  rupture
