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.

Target acquisition algorithm based on Sliding Mode Control (SMC) is proposed for TV tracking system. Target acquisition capability and performance are both improved attributing to overcoming the deficiencies of traditional linear control. In this paper sliding surface with variable coefficient and continuous control law without switching is introduced in the SMC controller design. The improved SMC shows better performance compared to basic SMC and full-field acquisition with rapid response and non-overshoot is achieved. The simulation of acquisition shows that the system can acquire a target passing through the view field of 1.53 in the width with an uniform speed of 15 /s while the whole process is in a short settling time and chattering-free and the reaching segment has no overshoot. 2010 IEEE.

A set special detecting system is proposed based on TDICCD push-broom technology applying in dynamic imaging detecting experiment of space optics remote sensor. In the system In the course of detecting push-broom movement of the satellite is simulated through using double supporting U structure precision rotary platform with remote sensor by angular speed 0.555/s regard Nyquist frequency target as detecting aim within the range of 5 and control precision on steady speed achieves 0.3% in order to solve matching uncertainty between the CCD pixel and the vertical target strip image when the remote sensor does push-broom make matching simplify enhance the measurement result the accuracy. So the tolerance a/n arithmetic progression gap target strip is joined in each group of rectangular vertical group target strip. The remote sensor obtains in vertical the level and 45 the direction 0 fields of view 0.86 the field of view Nyquist frequency target strip image after detected a group target strip which can precision matching to TDICCD pixel at least can be obtained through analysis and dealing with 0.86 field of view's target strip image. The experiment not only verifies the detecting system's feasibility but simultaneously verifies whether to have the high quality dynamic imaging quality when TDICCD push-broom technology is adopted on the remote sensor developed. 2010 Copyright SPIE - The International Society for Optical Engineering.

In view of the low speed the heavy load reversing the frequently brake the intense impact characteristics of AOD furnace tilting system The double closed-loop with feedforward is used. Position regulator and speed regulator use PID algorithm.And the speed loop is designed based on vector control. This control system was simulated by MATLAB Simulink software. The simulation result showed: Adjustment time is 8s the position steady-state error is 0 so it has achieved the demanded target of 0.12 radian static error fully. 2010 IEEE.

In view of domestic traffic the traffic flow is increasing rapidly recent years whereas the traffic control is deficient. This paper presents a design of intelligent traffic control system based on DSP and Nios II. Using Dual-CPU Intelligent Traffic Control System combined with logic control in FPGA implements kinds of functions which include crossphase adjustment exchanging and establishing related information live human-computer interaction and remote control etc. The system works mostly at the mode of timing and multiple phases according to the user demands dynamically thus it breaks through the bottleneck of traditional traffic signal controller and can accomplish the control in complicated and diversified traffic. This paper gives the realization of hardware system as well as the software system. The experiment results show that the Intelligent Traffic Control System can completely meet the requirements of modern traffic control. 2009 IEEE.

The design method and result are described for an infrared afocal zoom system. Its zoom ratio is 4 (2) Functions such as changing the field-of-view and the corresponding field of view is 3-12. The working waveband is from 7.5m to 10.5m focusing for objects at finite distances and athermalizing the system can be achieved by axially moving a single element in the system. and its total length is required to be no more than 350mm. The final optical system consists of 7 elements with aspheric surfaces and a diffractive optical element. It achieves diffraction-limited imaging at the far infrared waveband. Two conclusions can be drawn from the design. (1) Using diffractive optical elements in the design of an infrared optical system is an effective approach to control color aberrations which eliminates the need to use exotic and expensive materials and helps to reduce the cost of the system
