	Three-loop autopilot design and simulation (EI CONFERENCE) 会议论文 OAI收割 2012 9th IEEE International Conference on Mechatronics and Automation, ICMA 2012, August 5, 2012 - August 8, 2012, Chengdu, China 作者: Zhang Y. 收藏 \| 浏览/下载：44/0 \| 提交时间：2013/03/25 In order to realize missile real-time change flight trajectory three-loop autopilot is setting up. The structure characteristics autopilot model and control parameters design method were researched. Firstly this paper introduced the 11th order three-loop autopilot model. With the principle of systems reduce model order the 5th order model was deduced. On that basis open-loop frequency characteristic and closed-loop frequency characteristic were analyzed. The variables of velocity ratio dynamic pressure ratio and elevator efficiency ratio were leading to correct system nonlinear. And then autopilot gains design method were induced. System flight simulations were done and result shows that autopilot gains played a good job in the flight trajectory autopilot satisfied the flight index. 2012 IEEE.
	Contact-impact analys with clearance hinge in flexible multi-body system (EI CONFERENCE) 会议论文 OAI收割 2nd Annual Conference on Electrical and Control Engineering, ICECE 2011, September 16, 2011 - September 18, 2011, Yichang, China Ge M.; Jia H.; Liu B. 收藏 \| 浏览/下载：52/0 \| 提交时间：2013/03/25 Hinge in mechanical systems exist small clearance and contact deformation After consideration of flexible components cause the system to the wear and tear impact force reduced at the clearance noise contact time increased vibration contact-impact areas expand and clearance also caused disturbance of the rod angular velocity of the linkage. 2011 IEEE. reliability reduce or even failure[1]. Therefore the hinge clearance and the impact of flexible components in kinetic models should be considered. In this paper a nonlinear spring-damper hinge clearance model is considered to establish mechanical system structure of dynamic equations[46] through a four-bar linkage hinge with multi-clearance rotation of ADAMS dynamic simulation for dynamics simulation study. Simulation results show that hinge clearance and link flexible in Four-link mechanism dynamics have a great impact on performance: connection with the clearance lead to pin holes to produce a series of collisions and a larger initial impact force
