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.

Based on the principle of gyroscope and the structure of gyro stabilized platform this paper gives the analysis and comparison of control strategies for stable platform included classical PID control and three kinds of advanced strategies: Fuzzy Control Sliding Mode Variable Structure Control and Active Disturbance Rejection Control. The compensation methods for stable platform's error are also discussed and evaluated based on the sources of error especially for the non-linear friction and gyro drift. The paper provides the reliable methods for recognizing and improving the accuracy of gyro stabilized platform from the control strategies and error compensations. 2011 Chinese Assoc of Automation.

A distributed embedded system is designed based on WES(Windows Embedded Studio) which is used to improve the stability and reliability of the aerospace optoelectronic reconnaissance platform and enhance the visualization in the complicated natural environment. This system is combined with the component of distributed data communication the component of CCD image acquisition and transfers all of which are designed on the hardware of PM401 by WES. Then plying the EWF technology integrate the stable and reliable distributed system. At last using NHPP mathematic model analyze the stability and reliability of the system. The results show that the stability and the reliability of this distributed system works well up to 94.61%. 2010 IEEE.

In order to reduce the size and weight of the gimbal in a traditional stable platform and correct the disadvantage in size of the payload the paper first improves the gimbal which is an important component of a stable photoelectric platform that also is an important factor in affecting the size and weight of a stability platform. In this paper a closed-form solution of 3-DOF manipulator is designed according mechanical arm design principles. This manipulator is formed by a three joint axes whose extended line is intersected at one point. A standard orthogonal coordinate system is set up for each rod in the manipulator. And then rotation transformation matrix expression is obtained. At last in this paper the manipulator arm-shaped method for solving solutions is description and also each parameter of the gimbal is calculated when the photoelectric detection devices at bottom reach the expected position. Test results show that the photoelectric stability platform with gimbal we designed is smaller lighter and simpler than that traditional. Also the packaging and size of the photoelectric will not be affected with this open structure. 2010 IEEE.

In order to meet the needs of measurement of highspeed target the timing sequence of LUPA300 an array CMOS image sensor of CYPRESS is analyzed. The driving timing and control software is designed for the array CMOS sensor. High speed CMOS imaging system whose hardware platform is FPGA is emphasized. Real-time non-uniformity correction for CMOS sensor is implemented in the output stage. The experimental result shows that the system could control the CMOS sensor flexibly. The image is clear and stable. The maximum resolution of the image is 640H480V pixels and the system can operate up to 250 frames per second in full resolution. 2010 IEEE.
