	A servo control system of dynamic target simulation device for aerial camera (EI CONFERENCE) 会议论文 OAI收割 2nd International Conference on Advanced Design and Manufacturing Engineering, ADME 2012, August 16, 2012 - August 18, 2012, Taiyuan, China 作者: Ji Q. 收藏 \| 浏览/下载：31/0 \| 提交时间：2013/03/25 This article introduces a dynamic target simulation device to evaluate dynamic image quality of the aerial camera. The device simulated the positional relationship of the sky and ground in the laboratory when aerial camera flies at high altitude. And it can be used to inspect camera image quality of aerial camera flying at high altitude in laboratory. At a same time the article focuses on this servo control system of device building a control model and giving control strategy. The servo control system was proved stably and reliably after experimental verification. And it provides a strong guarantee for the test of the dynamic image.

	Research on the the device of non-angular vibration for opto-electronic platform (EI CONFERENCE) 会议论文 OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Smart Structures and Materials in Manufacturing and Testing, April 26, 2010 - April 29, 2010, Dalian, China An Y.; Song C.-P.; Kuang R.-J.; Jin G. 收藏 \| 浏览/下载：31/0 \| 提交时间：2013/03/25 The opto-electronic platform is the main equipment for aviation reconnaissance. It is a surveillance system with the function of search recognition orientation and tracking by opto- electronic instruments. It is made up of opto-electronic instruments which are used to get high quality image and stabilization tracking system to control stabilization and gesture of platform for exact tracking. The opto-electronic platform purpose is to achieve high quality image. Besides the impact of optic system the image quality of the system is influenced greatly in the vibration environment. The research worked by Zhao peng which demonstrated the affection caused by angular vibration was worse than which caused by line vibration and what was multiplied direct ratio with plane altitude. So it is necessary to design a new device which could be used widely and has good angular vibration isolation effect. According to the theory of parallelogram the non-angular vibration device had been designed with spatial links and the theory of non-angular vibration was analyzed. The three-dimensional model was set with UG the analysis was done by ADAMS/vibration software. The acceleration and displacement response of the device in each direction was calculated by inspiriting it with sine wave of the acceleration in three directions and the stiffness and damp were studied. All the work prove the design principle of the device is reasonable and the device is adopted to keep the platform motion moving horizontally at the meantime the device is good at isolating vibration in all directions. 2010 SPIE.
	Innovative EDL GNC scheme for precise and safe mars landing missions (EI CONFERENCE) 会议论文 OAI收割 60th International Astronautical Congress 2009, IAC 2009, October 12, 2009 - October 16, 2009, Daejeon, Korea, Republic of 作者: Liu Y.; Zhang L.; Zhang L.; Liu Y.; Liu Y. 收藏 \| 浏览/下载：44/0 \| 提交时间：2013/03/25 Future mars missions plan to land the more massive spacecrafts on the higher altitude and hazardous region the landers should have the capability of high-precision autonomous navigation guidance and control (GNC) and automatic obstacle detection and avoidance to explore the scientific but hazardous region. The traditional deep space network (DSN) based GNC mode used in the Mars entry descent and landing (EDL) phase has no ability to meet this goal so the novel EDL GNC scheme is required to achieve the precise and safe Mars landing. This paper proposes the innovative Mars EDL GNC system scheme and the emphases are focused on the EDL navigation guidance and control with high landing accuracy and autonomous obstacle detection and avoidance.
