To deal with the defects of BP neural networks used in balance control of inverted pendulum
such as longer train time and converging in partial minimum
this article reaLizes the control of double inverted pendulum with improved BP algorithm of artificial neural networks(ANN)
builds up a training model of test simulation and the BP network is 6-10-1 structure. Tansig function is used in hidden layer and PureLin function is used in output layer
LM is used in training algorithm. The training data is acquried by three-loop PID algorithm. The model is learned and trained with Matlab calculating software
and the simuLink simulation experiment results prove that improved BP algorithm for inverted pendulum control has higher precision
better astringency and lower calculation. This algorithm has wide appLication on nonLinear control and robust control field in particular. 2011 IEEE.

The remote sensing camera in large field and wide cover needs CCD with enough pixels. But the existing CCD cannot satisfy the practical needs. Therefore several pieces of CCD which has insufficient pixels are spliced to get a long CCD array with plenty of pixels. The precision requirements of CCD splicing are very strict
so that the same high accuracies are required in the precision detection of CCD splicing. When detecting precision of CCD splicing
the graphical markers with simple geometric structure in the CCD package are selected as templates. The position precision data of the graphical markers in each CCD are obtained using the template matching algorithm. Using the unified objective templates
the focal plane which has multi-chip of CCD is detected by template matching algorithm. Experiment results show that the template matching algorithm can enhance the located precision of each CCD to 0.347m. The splicing precision detection with template matching algorithm can avoid the subjective error caused by the conventional detection method. And its results are more accurate. In addition
without manual intervention in the process of precision detection
the efficiency of precision detection is improved. 2011 IEEE.

The characteristic of the drift error of inertial platform is a high-order nonlinear dynamic system
using the neural networks' abilities of universal approximation of differentiable trajectory and capturing system dynamic information
this paper presents the drift error identifying project of inertial platform based on Elman networks structure. First
the drift error model of inertial platform is established
after selecting the input and output for network
momentum and alterable speed algorithm is used to speed up the network convergence. On the basis of the algorithm
the extended nonlinear node function in the hidden network does not only improve the learning speed of network
but also satisfies the need of accuracy on system identification. Through the drift error data measured on inertial platform
the training result shows that the scheme achieves satisfied identification results. (2011) Trans Tech Publications.

The traditional sorting algorithm of median filtering is optimized according to the hardware structure features of FPGA. FPGA is used to acquire the data parallelly for comparing the data of the same column in the median filtering window. Comparing results shared by adjacent filter window are saved temporarily to match the new round of median filtering by using FPGA internal resources. This method can reduce the comparing times from current 21 down to 13
and improve the algorithm efficiency nearly 40%.The experimental results prove that the optimized algorithm can filter a 1K1K gray-level image in about 20ms
which ensure the proposed algorithm can be applied in the real-time image median filtering system. 2010 IEEE.

The paper introduces the white-light spectral scanning interferometry for surface measurement. This interferometry can be used to measure the roughness of both smooth surfaces and those with large step heights. This real-time surface measurement can be achieved using acousto-optic tuneable filtering (AOTF) technique without mechanical scanning. At first
the structure and principle of this interferometry is introduced. Then the algorithm of the surface roughness measurement is proposed. What's more
the experiment with standard test piece is conducted. Compared with the traditional laser-light interferometry
the data shows that the proposed method has a higher accuracy which is proved to be nano-scale. A conclusion is given at last in which the superiorities and the limitations of the proposed system were discussed. 2010 SPIE.

Munsell color system is selected to establish the mutual conversion between RGB and L*a*b* color model for camera. The color luminance meter and CCD camera synchronously measure the same color card
XYZ value is gotten from the color luminance meter
the training error is 0.000748566
it can show that the method combining second general revolving combination design with genetic algorithm can optimize the hidden-layer structure of neural network. Using the data of testing set to test this network and calculating the color difference between forecast value and true value
the color picture captured from CCD camera is expressed for RGB value as the input of neural network
and the L*a*b* value converted from XYZ value is regarded as the real color value of target card
which the difference is not obvious comparing with forecast result
the maximum is 5.6357 NBS
namely the output of neural network. The neural network of two hidden-layers is considered
the minimum is 0.5311 NBS
so the second general revolving combination design is introduced into optimizing the structure of neural network
and the average of color difference is 3.1744 NBS.
which can carry optimization through unifying project design
data processing and the precision of regression equation. Their mathematics model of encoding space is gained
and the significance inspection shows the confidence degree of regression equation is 99%. The mathematics model is optimized by genetic algorithm
optimization solution is gotten
and function value of the goal is 0.0007168. The neural network of the optimization solution is trained
