In the process of producing glass feet billet how to detect the qualification of the products has became an important part. For this situation this paper designs a detection system of the linear of glass feet billet. In this system first make Sobel edge detection to the images from the camera. Then this paper proposes a dynamic threshold segmentation method this method can draw the upper edge curve of the glass feet billet quickly and accurately. This method can detect the qualification of the products very accurate. This system has been successfully applied to the products site. 2012 IEEE.

A nonlinear control strategy for controlling a motion system with mechanical resonance is presented in this paper. A mathematical model of the servo system is derived according to the parameters of an actual system. By using two Tracking-Differentiators reference input and system output are tracked and their differential signals are given simultaneously. A nonlinear PD control law in velocity loop is designed based on non-smooth feedback. The simulation results show that the control law is superior remarkably in performance to linear PD control law and the classical PID control law. Tracking-Differentiator resolves the contradiction between rapidity and overshoot of system response. The nonlinear PD control law improves system dynamic performance and intensifies the ability of disturbance rejection. The control design achieved in this paper makes the servo system more robust. 2010 IEEE.

Space optical remote sensor is very important in many fields of science and military significance. It is widely applied. Space optical remote sensor design and manufacturing require precision and stability. Focusing mechanics is an important component of remote sensors. Focusing mechanics can guarantee the stability of the entire mechanics focusing accuracy therefore the stability of research focusing mechanics is very important. In order to guarantee the space optics remote sensor focusing mechanics the stability takes steps the space optics remote sensor focusing organization mechanics characteristic analysis from the classics contact theory. This article uses international general non-linear finite element analysis software ABAQUS to carry on mechanics characteristic analysis to the space optics remote sensor focusing mechanics. First acts according to the focusing mechanics unique feature carries on the finite element to the structural model the grid division the material attribute disposition and the boundary condition indeed grades. Then establishment contact non-linear finite element model and to focusing organization finite element model infliction unit action. Like this contacts the result and the equivalent static analysis result which the nonlinear analysis obtains carries on the contrast and the analysis. This article last count result modality is 90HZ satisfies the space optics remote sensor structure overall modality to request to be bigger than 50HZ.This article when carries on the dynamic analysis extracts the structure kinetic energy and the acceleration curve. In the dynamic analysis obtained transient response analysis modality 70.5Hz this also is bigger than 50HZ. The dynamic analysis indicated the structure dynamic stability has the distinct enhancement has provided certain foundation for the space optics remote sensor following development work reduced the overall system development cycle. 2009 SPIE.

In order to measure dynamic interpolation errors of photoelectric encoder of high precision the dynamic evaluation system of interpolation errors is introduced. Firstly the fine Moire signal of encoder which is collected with the high-speed data gathering card into the computer is treated to equiangular data with the method of linear interpolation. Then the analysis of harmonic wave with the FFT is processed. Compared with the standard signal the dynamic interpolation errors of the encoder are calculated. Experimental results show that the precision of the dynamic evaluation system of interpolation errors is 0.1 %( pitch). The evaluation system is simple fast high precision and can be used in the working field of the encoder. 2009 SPIE.
