	Longitudinal control law design and simulation of fixed-wing UAV (EI CONFERENCE) 会议论文 OAI收割 2012 International Conference on Measurement, Instrumentation and Automation, ICMIA 2012, September 15, 2012 - September 16, 2012, Guangzhou, China 作者: Duan Z. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 Taken some fixed-wing UAV as the study object the aircraft movement was broken down into the longitudinal movement and lateral movement according to the linearized small perturbation principle the longitudinal control law design method was discussed using root locus which belonged to classical control theory. The six degrees of freedom nonlinear model simulation result shows that: the control parameters designed are reasonable the simulation profile is fully consistent with the setting profile the control effect of pitch angle loop and altitude loop meets with the indices requirements the method is mature and reliable easy to realize in engineering.

To achieve synchronic output of each axis applied the multi-body dynamic application ADAMS to realize its parametric modeling and optimization finally got the appropriate parameters to satisfy the performance. Then researched the parameters affection to synchronic performance completed the initial design of the actuator transmission system. 2011 IEEE.
	Double-swing method used for polishing off-axis aspherical mirrors (EI CONFERENCE) 会议论文 OAI收割 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Advanced Optical Manufacturing Technologies, November 19, 2008 - November 21, 2008, Chengdu, China 作者: Chen Y.; Song S.-M.; Xuan B.; Wang P.; Li J.-F. 收藏 \| 浏览/下载：45/0 \| 提交时间：2013/03/25 Based on the characteristics of off-axis aspherical surface the comparison of simulation effects under different parameters is made. In order to achieve optimal parameters a new method used for polishing off-axis aspherical mirrors-Double-Swing Method (DSM) is proposed in this paper a high order off-axis rectangle aspherical mirror has been polished by DSM. The final result of profile measurements of 12nm and the polishing mechanism of DSM is introduced. The mathematical model of the DSM with steady movement state is established.The movement of this mathematical model is simulated in a programming language RMS is achieved. The result indicates that the method is of practice and has even higher working efficiency and precision. 2009 SPIE.
