Performance Analysis and Evaluation of Geometric Parameters in Stereo Deflectometry Article

Yongjia Xu, Feng Gao, Xiangqian Jiang

Engineering 2018, Volume 4, Issue 6,   Pages 806-815 doi: 10.1016/j.eng.2018.10.007

Abstract:

This paper presents a novel geometric parameters analysis to improve the measurement accuracy of stereo deflectometry. Stereo deflectometry can be used to obtain form information for freeform specular surfaces. A measurement system based on stereo deflectometry typically consists of a fringe-displaying screen, a main camera, and a reference camera. The arrangement of the components of a stereo deflectometry system is important for achieving high-accuracy measurements. In this paper, four geometric parameters of a stereo deflectometry system are analyzed and evaluated: the distance between the main camera and the measured object surface, the angle between the main camera ray and the surface normal, the distance between the fringe-displaying screen and the object, and the angle between the main camera and the reference camera. The influence of the geometric parameters on the measurement accuracy is evaluated. Experiments are performed using simulated and experimental data. The experimental results confirm the impact of these parameters on the measurement accuracy. A measurement system based on the proposed analysis has been set up to measure a stock concave mirror. Through a comparison of the given surface parameters of the concave mirror, a global measurement accuracy of 154.2 nm was achieved.

Analysis of Control Performance of ECS in Fighter Plane

Yao Hongwei,Wang Jun

Strategic Study of CAE 2006, Volume 8, Issue 6,   Pages 44-47

Abstract:

Based on the characteristics of the ECS, pulse width-fuzzy control concept was put forward. Four models, pulse width regulating, PID control, fuzzy control and combined control, were established with Fuzzy and Simulink tool boxes in MATLAB. The difference between the temperatures of mixed flow and the objective and its change rate were the input in the fuzzy system, and the output, the control signal, was obtained by fuzzy reasoning. Rank skipping response characteristics of the four control methods were computed and analyzed with temperature rank skipping signal. A group of dynamic parameters were selected as the input data, by which dynamic response of the combined control model was simulated. The result showed that combined control system could solve the problem of temperature fluctuation in existing pulse width regulating system efficiently.
