Based on the principle of gyroscope and the structure of gyro stabilized platform
this paper gives the analysis and comparison of control strategies for stable platform included classical PID control
and three kinds of advanced strategies: Fuzzy Control
Sliding Mode Variable Structure Control and Active Disturbance Rejection Control. The compensation methods for stable platform's error are also discussed and evaluated based on the sources of error
especially for the non-linear friction and gyro drift. The paper provides the reliable methods for recognizing and improving the accuracy of gyro stabilized platform from the control strategies and error compensations. 2011 Chinese Assoc of Automation.

Image super-resolution methods process an input image sequence of a scene to obtain a still image with increased resolution. Classical approaches to this problem involve complex iterative minimization procedures
typically with high computational costs. In this paper is proposed a novel algorithm for super-resolution that enables a substantial decrease in computer load. First
decompose and reconstruct the image by wavelet packet. Before constructing the image
use neural network in place of other rebuilding method to reconstruct the coefficients in the wavelet packet domain. Second
probabilistic neural network architecture is used to perform a scattered-point interpolation of the image sequence data in the wavelet packet domain. The network kernel function is optimally determined for this problem by a MLP-PNN (Multi Layer Perceptron - Probabilistic Neural Network) trained on synthetic data. Network parameters dependent on the sequence noise level. This super-sampled image is spatially Altered to correct finite pixel size effects
to yield the final high-resolution estimate. This method can decrease the calculation cost and get perfect PSNR. Results are presented
showing the quality of the proposed method. 2008 IEEE.

A new method of affine object recognition and affine parameters estimation is presented. For a real-time image and a group of templates
in addition
firstly
on the basis of correct recognition
we segment the object regions in them and compute their covariant matrices. Secondly
it can estimate affine parameters exactly
normalize the ellipse regions defined by covariant matrices to circle regions to get rotational invariants
and the estimated error is within 3%. 2008 IEEE.
and compute the similarity function value between rotational invariants of real-time image and every template respectively. Then compare the values with threshold set in advance
if more than one value is larger than threshold
take the corresponding templates as candidates
and compute affine matrix between real-time image and every candidate. Finally
transform the realtime image with every affine matrix and match the result with corresponding candidate by classical matching methods. Experimental results show that the presented method is robust to illumination
with low computational complexity
and it can realize recognition of different affine objects

Classical methods for designing a controller depend on the accuracy of system model. However
plant's models and other parts in a physical system can not accurately represent all possible dynamics. Thus the controller designed is usually not the optimal one. In this article
a new
simple adaptive control method
which combines the classical frequency domain method with the neural network theory
is proposed. Firstly
we can obtain a controller using classical method. Secondly we use the coefficients in digitized controller equation as the initial values of an Adaline network. Finally
LMS learning rules is used to adjust the weights adaptively. Experimental results show that this method is very effective in improving the performance of conventional controller. 2006 IEEE.
