By designing the double loop configuration  the autonomous trajectory tracking is realized. The model uncertainty  external disturbance and the senor noise are also taken into consideration. Then the H controller is put forward in the inner loop. An optimal stability augmentation control (SAC) method is used to stabilize the horizon position and keep it away from oscillation. By calculating the nonlinear decouple map  control quantity is converted to the speeds of the four rotors. At last some simulation results and the prototype implementation prove that the control method is effective.   Image forward motion compensation method for some aerial reconnaissance camera based on neural network predictive control (EI CONFERENCE) 会议论文  OAI收割 International Conference on Advanced Research on Computer Science and Information Engineering, CSIE 2011, May 21, 2011 - May 22, 2011, Zhengzhou, China Zhong C.; Ding Y.; Fu J. 收藏  |  浏览/下载：28/0  |  提交时间：2013/03/25 In this paper  neural network predictive control method is used to compensate the image forward motion of a certain aerial reconnaissance camera and we have solved several problems that traditional control methods have. Firstly  according to the principle of imaging  we analyzed the reasons for the existence of image forward motion and established the mathematical model. Secondly  we analyzed the theoretically feasibility of the method. At last  simulation  experiments and test are used to validate the practical feasibility. Through what we have done  we conclude that neural network predictive control method can be used to compensate image forward motion for this certain camera and can make a perfect performance. 2011 Springer-Verlag.   Study of large scale large power control source electromagnetic with "earth-ionosphere" mode 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2010, 卷号: 53, 期号: 2, 页码: 411-420 作者:  Li Di-Quan;  Di Qing-Yun;  Wang Miao-Yue   |  收藏  |  浏览/下载：24/0  |  提交时间：2018/09/26 "earth-ionosphere" Mode  Large Power  Large Offsets  Electromagnetic Field  Forward  Numerical Simulation   Study of large scale large power control source electromagnetic with "earth-ionosphere" mode 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2010, 卷号: 53, 期号: 2, 页码: 411-420 作者:  Li Di-Quan;  Di Qing-Yun;  Wang Miao-Yue   |  收藏  |  浏览/下载：17/0  |  提交时间：2018/09/26 "earth-ionosphere" Mode  Large Power  Large Offsets  Electromagnetic Field  Forward  Numerical Simulation   Method of improving the accuracy of image motion measurement for panoramic aerial cameras (EI CONFERENCE) 会议论文  OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optoelectronic Materials and Devices for Detector, Imager, Display, and Energy Conversion Technology, April 26, 2010 - April 29, 2010, Dalian, China 作者:  Jia P. 收藏  |  浏览/下载：24/0  |  提交时间：2013/03/25 To improve the accuracy of image motion measurement for panoramic aerial cameras  the paper proposed a method of real-time image motion measurement based on 2D spatial correlation. An auxiliary area CCD is positioned paralleled to the main linear TDI CCD in the focal plane of the camera. For every frame of the image sequence taken by the auxiliary CCD  a prediction on the displacement of the current image in the flight direction is made based on the forward image motion velocity. The current and the reference images are combined together for 2D-correlation  which products an image motion vector. By decomposing the vector  both the forward and pendulum-swing image motions can be determined. The demanding computational requirements for the real-time 2D-correlation are covered by a joint transform optical correlator. Simulation test results show that the accuracy is improved and the measurement error is within 0.2 pixels for input images with SNR=1 dB. 2010 Copyright SPIE - The International Society for Optical Engineering.   The research on servo control technology of O-E theodolite based on angular acceleration sensor (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Wei L.; Jin G.; Juan C. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 A new servo control methods for O-E theodolite is presented in this paper. The methods integrates optimally feed forward and feedback control  and adopts acceleration delay compensation based on velocity delay compensation  then achieves servo control of O-E theodolite effectively. Furthermore  Angular acceleration sensor is applied as information resources  and adaptive filter is formed to provide with feed forward control signal in the methods. For double closed loop servo control system of O-E theodolite  the location correction loop and velocity correction loop are analyzed and designed. Simulation and experimental results show that comparing with traditional methods  this servo control methods can improve significantly tracking precision and stability of O-E theodolite. 2010 IEEE.
