Correctness and validity of arithmetic are analyzed. With flight dynamics  the roll-loop mathematic model and reference model are established. Sliding hyperplane is deduced based on model reference sliding mode variable structure theory. Combing with reaching law  control law is derived  and stability of roll-loop is analyzed. Chattering of aileron instructions is alleviate by using boundary layer approach. Digital flying simulation result shows that variable structure control arithmetic realized roll stabilization control  the roll angle is less than 5.3 under powered flight  and that of unpowered flight is less than 0.5  respectively. The command fin angle is less than 1.5. High frequency chattering of fin command nearby the minimum velocity was trailed off by chattering reduction arithmetic. The sliding mode control arithmetic show good performance when aerodynamic coefficients varies 20%. The control arithmetic is easy to be implemented for its simplicity. 2011 IEEE.   Isometries in hyperbolic spaces 期刊论文  OAI收割 SCIENCE CHINA-MATHEMATICS, 2010, 卷号: 53, 期号: 1, 页码: 71-86 作者:  Huang ManZi;  Wang XianTao;  Wang YueFei   |  收藏  |  浏览/下载：23/0  |  提交时间：2018/07/30 surjective map  geodesic  hyperplane  isometry  Mobius transformation   Application of support vector machine combined with K-nearest neighbors in solar flare and solar proton events forecasting 期刊论文  OAI收割 ADVANCES IN SPACE RESEARCH, 2008, 卷号: 42, 期号: 9, 页码: 1469-1474 作者:  Li, Rong;  Cui, Yanmei;  He, Han;  Wang, Huaning 收藏  |  浏览/下载：27/0  |  提交时间：2017/06/20 Feature space  Prediction accuracy  Separating hyperplane   Reducibility of hyperplane arrangements 期刊论文  OAI收割 SCIENCE IN CHINA SERIES A-MATHEMATICS, 2007, 卷号: 50, 期号: 5, 页码: 689-697 作者:  Jiang, Guang-feng;  Yu, Jian-ming;  Jianming YU   |  收藏  |  浏览/下载：17/0  |  提交时间：2018/07/30 hyperplane arrangement  irreducible component  logarithmic derivation
