The stabilization control principle block diagram of semi-strapdown seeker is shown based on the stabilization equation. The main influence factors of the stability precision are pointed out  such as friction disturbance  velocity measurement noise and missile disturbance. For the sake of improving the stabilization precision and tracking precision  disturbance observer was proposed in the inner loop of semi-strapdown seeker servo-control system. The low frequency external disturbance and high frequency velocity measurement noise are effectively restrained by the disturbance observer as shown in hardware-in-loop simulation  and optical axis stabilization precision and tracking precision are greatly improved. 2011 IEEE.   Optical axis stabilization of semi-strapdown seeker based on disturbance observer (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Information and Automation, ICIA 2011, June 6, 2011 - June 8, 2011, Shenzhen, China Sun G.; Zhu M.; Yin S.; Jia H. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 Based on the kinematics of semi-strapdown seeker  the framework coordinate of the seeker is established. The optical axis stability equation of semi-strapdown seeker is deduced by using attitude transformation matrix. Then  the stability control principle block diagram of semi-strapdown seeker is shown based on the stability equation. The main factors that influence the stabilization precision are pointed out  such as friction disturbance  velocity-measuring noise and missile disturbance. In order to improve the stabilization precision  disturbance observer was proposed in semi-strapdown seeker stability control. The low frequency external disturbance and high frequency velocity measurement noise are effectively restrained by the disturbance observer as shown in hardware-in-loop simulation  and optical axis stabilization precision is improved nearly 20 times and 5 times due to two different frequencies with same amplitude. 2011 IEEE.   Target characteristic extraction algorithm based on block structure variables (EI CONFERENCE) 会议论文  OAI收割 2010 3rd International Conference on Advanced Computer Theory and Engineering, ICACTE 2010, August 20, 2010 - August 22, 2010, Chengdu, China 作者:  Zhou Y.;  Yang H.;  Yan F.;  Yan F. 收藏  |  浏览/下载：28/0  |  提交时间：2013/03/25 In image processing system  the target recognition is very crucial. An optimized algorithm based on the definition of block is presented. In this algorithm  two structure variables are self-defined to calculate the areas and centroids of targets. The labeling conflicts are resolved by tracking and correcting  which means that if there is a conflict  trace the neighbored blocks and correct the labels of them. Finally  the characteristics of blocks  which have the same label  are accumulated. This method has outstanding advantages in saving memory  compared with Pixel labeling algorithm and Run-length code algorithm. The new algorithm is simple and the results of target characteristics are easy to be analyzed and handled in the following processes. 2010 IEEE.
