	The fuzzy comprehensive evaluation of laser weapon system combat effectiveness (EI CONFERENCE) 会议论文 OAI收割 2012 3rd International Conference on Mechanical, Industrial, and Manufacturing Technologies, MIMT 2012, March 24, 2012 - March 25, 2012, Shenzhen, China Li H.; Guo L. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 To evaluate the laser weapon system's combat effectiveness which is related with so many factors is a very complex issue. In this paper by analyzing the factors which influence the laser weapon system an index system for the laser weapon system comprehensive evaluation of the combat effectiveness is built up. The method of calculating weight the improved analytic hierarchy process is introduced. The evaluation model of improved fuzzy-AHP is established and the feasibility and the validity of the proposed evaluation method is validated through a practical example.

	The stability design and realization of airborne platform based on TMS320F2812 (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China 作者: Zhang X.; Zhang X.; Zhang X. 收藏 \| 浏览/下载：48/0 \| 提交时间：2013/03/25 Airborne electro-optical stable platform can isolate movement and vibration of the airframe stabilizes the optic axis of the photoelectic detector realize the observation and tracking for the object. It has comprehensive application value in army and cicil field. Most of present airborne platforms are analogic control system digital control system can improve the system general performance digital control is the development direction of platform systems. In view of the requirements of isolating disturbances and stabilizing optical axis of high-precision photoelectric guidance system a three-axis stabilized platform system centering on the rate gyro was designed. The disturbance-isolation theory of the stabilized platform was analyzed and the control structure including multiple closed-loops was designed. At last a controller of the servo system based on TMS320F2812 DSP has been designed. Experiment results meet the technical index and precision requirement and illustrate the practicability and effectiveness of the scheme. 2011 IEEE.
