	Research on satellite platform vibration compensation technology for space optical communication (EI CONFERENCE) 会议论文 OAI收割 2012 International Meeting on Opto-Electronics Engineering and Materials Research, OEMR 2012, July 27, 2012 - July 29, 2012, Shenyang, Liaoning, China Han C.; Li X. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 The piezo-electric steering control system is used to compensate the vibration of satellite platform. The mathematical model of piezo-electric steering system is built. The adaptive controller based on improved LMS filter algorithm is designed according to this system characteristic. The adaptive delay filter is designed to solve slow convergence speed problem of traditional algorithm. Meanwhile the adaptive delay filter can also compensate phase delay of control circuit. The adaptive deviation filter is introduced and it effectively compensates the vibration deviation which is low frequency and high amplitude. The experimental results show that the remained errors are rad which meets space optical communication requirement and proves that this control scheme is valid and feasible.

	Composite-structure frequency selective surface with tripole elements (EI CONFERENCE) 会议论文 OAI收割 8th International Symposium on Antennas, Propagation and EM Theory, ISAPE 2008, November 2, 2008 - November 5, 2008, Kunming, China 作者: Gao J. 收藏 \| 浏览/下载：72/0 \| 提交时间：2013/03/25 Two composite symmetry structure is proposed in this paper. Based on the integral equation method the frequency response with large incident angle effect is analyzed. As a result of the numerical analysis it is shown that the composite symmetry structure with single FSS screen is efficient to stabilize the drift of FSS resonant frequency with the steering of incident angle though transmission loss increased. Especially the structure that the FSS is embedded centrally in the dielectrics has better frequency characteristic with flat top and sharp skirts. The studies have indicated the versatility of the proposed structure. 2008 IEEE.
	Research on shaftless fast-steering mirror used in a precision tracking-aiming system (EI CONFERENCE) 会议论文 OAI收割 3rd International Symposium on Advanced Optical Manufacturing and Testing Technologies, AOMATT 2007: Large Mirrors and Telescopes, July 8, 2007 - July 12, 2007, Chengdu, China 作者: Wang Y.; Guo J.; Guo J.; Wang Y.; Wang Y. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 Based on the analysis of principle of tracking and aiming system some important factors to design the structure of tracking-aiming system and the layout of optical system are discussed. Besides the paper gives the present developing situation of fast-steering mirror at home and abroad analyzes the advantages and disadvantages of FSM with axis and presents a novel design of flexible axis FSM. The main axis of composite axis system is tracked by motor to drive the frame and the sub-axis is tracked by voice coil motor (VCM) to drive FSM. The structure of FSM and designing principle of VCM are introduced and the emulation analyses of inherent frequency and deformation under load of the FSM with software COSMOS are also given.
