In the process of detecting the fiber quality, the effect of optical collimation is directly related to the measurement results. The collimation of optical path can be realized by manual adjustment, but it takes one and a half hours to complete collimation and measurement, and the average standard deviation of the measured divergence angle is 0.0712. In order to solve the problem of manual adjustment,...
In order to estimate the attitude angle accurately, improve the accuracy of attitude and heading reference system(AHRS), aiming at larger errors of extended Kalman filter(EKF) in estimating attitude angle, a method based on iterative LM-CDKF algorithm has been proposed to estimate the attitude angle. In the paper, iterative filtering theory and Levenberg-Marquardt method is introduced into the central...
In order to develop the bottom driver software more rapidly and efficiently which are used in automotive battery management system and to get rid of high dependence on the hardware and low reusability of the drivers in automobile controller, this paper puts forward a kind of driver design method based on automotive open system architecture (AUTOSAR). Simulation modeling module has been made with the...
The paper introduces the research of tube-type bottle defects detection algorithm based on machine vision system, and the implementation method of detection system using machine vision and digital image processing technology. Industrial camera is used to collect the image of tube-type bottle, then the image is processed and analyzed by image processing technology. On this basis, by comparing with...
In order to estimate the accurate and real-time dynamic battery state of charge (SOC), owing to greater errors of extended Kalman filter (EKF) in estimating SOC, a method has been proposed to estimate the battery SOC based on LM-ICDKF algorithm. By using the two order RC equivalent circuit model, the MATLAB simulation tools are used to simulate the algorithm, this paper compares LM-ICDKF algorithm...
In order to measure the fiber parameters accurately and quickly, a kind of optical fiber beam collimation system is studied in this paper. The center of the beam image captured by the CCD camera is fed to the FPGA. Then the FPGA using the fuzzy self-tuning PID to controls multi-dimensional electric platform so that making the fiber vertical to the camera surface and achieving the beam automatic collimation...
By making the photovoltaic array operate at the peak power which depends on solar and ambient temperature, the maximum power point tracking techniques can significantly improve the efficiency of photovoltaic power generation. In this paper, the mathematical model of photovoltaic cells in arbitrary environment is built with the parameters and simulated and verified on Matlab/Simulink. Then, aiming...

The existing cloud model similarity calculation methods have the problems of low discrimination and high computational-complexity. Thus, a simplified method is proposed to calculate similarity by approximating the overlapping part of the cloud as triangle. In the premise of that the method can be effectively applied to one-dimensional cloud model, one-dimensional degree is averaged and multiplied...
The oxidation of ethylbenzene with 30% aqueous hydrogen peroxide (H 2 O 2 ) in an acetone–water medium at 30°C was investigated using hexadentate 8-quinolinolato manganese(III) complexes (Q 3 Mn III ) as catalysts. The results indicated that the Q 3 Mn III complexes, with ammonium acetate and acetic acid as additives, selectively catalyzed the side chain...
