Fuzzy control is used to solve the problem of fast tracking and overshoot since its essence belongs to PD control In order to improve the performance of system in low speed  a method named variance-gain adaptive algorithm is introduced in this paper. It defines the amplifier gain as a function whose independent variable is speed  so the amplifier gain can automatically be adjusted with the change of speed. When the turntable runs at low speed  it has a big amplifier gain  a good rigidity and high tracking accuracy. When the turntable runs at high speed  the method can control the amplifier gain and ensure the system dynamic performance. Design and implementation of these algorithms is introduced in detail. Experiment results show that the Flight Simulation Turntable has achieved the required performance through using fuzzy control algorithm and variance-gain adaptive algorithm. 2008 IEEE.   Morphology, echolocation and foraging behaviour in two sympatric sibling species of bat (tylonycteris pachypus and tylonycteris robustula) (chiroptera : vespertilionidae) 期刊论文  iSwitch采集 Journal of zoology, 2007, 卷号: 271, 期号: 3, 页码: 344-351 作者:  Zhang, L.;  Liang, B.;  Parsons, S.;  Wei, L.;  Zhang, S. 收藏  |  浏览/下载：25/0  |  提交时间：2019/05/10 Echolocation calls  Flight speed  Foraging behaviour  Resource partitioning  Tylonycteris pachypus  Tylonycteris robustula  Wing morphology   High-speed CCD camera system for the measurement of flight time of cannonballs (EI CONFERENCE) 会议论文  OAI收割 2005 Beijing International Conference on Imaging: Technology and Applications for the 21st Century, May 23, 2005 - May 26, 2005, Beijing, China 作者:  Gong Y. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 We have built a high-speed  sensitive camera system to capture the image sequence of cannonballs with accurate time reference  which can measure the flight time of cannonballs between leaving the cannon and explosion precisely. The camera system is composed of two identical cameras of high frame frequency linear CCD calibrated with the same time base. In this paper we present the operating principle of the camera system and discuss the scheme of high-speed processing of volumes of image data. The real-time measurement less than 1 millisecond can be achieved by the proposed approach.
