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.   Experimental investigation of Reynolds stress complex eddy viscosity model for coherent structure dynamics 期刊论文  OAI收割 Science China-Physics Mechanics & Astronomy, 2011, 卷号: 54, 期号: 7, 页码: 1319-1327 作者:  Jia YX;  Tang ZQ;  Jiang N(姜楠) 收藏  |  浏览/下载：20/0  |  提交时间：2012/04/01 Turbulent Boundary Layer  Coherent Structure  Complex Eddy Viscosity Model  Reynolds Stress  Phase Difference  Turbulent-Boundary-Layer  Wave
