第一章 概述
辨识(Identification)、状态估计和控制理论在现代控制理论中是密不可分的,它们互相渗透。辨识和状态估计离不开控制理论的支持,控制理论的应用几乎不能没有辨识和估计技术。由此可见,辨识在科研与实际应用领域都有很高的实用价值。
所谓辨识,就是从含有噪声的输入、输出数据中提取被研究对象的数据模型。此数据模型只是过程的输入输出特性在某种意义下的近似,而近似的准确度一般取决于采样数据的精度以及辨识方法的合理性。
辨识的目的是根据过程所提供测量的数据等信息,在某种准则意义下,估计出模型的未知参数,其基本原理如图1.1所示:
(Identification (Identification), state estimation and control theory in modern control theory are inextricably linked, they penetrate each other. Identification and control of state estimation theory is inseparable from the support of the application of control theory can hardly no identification and estimation techniques. This shows that the identification of the research and practical application areas have high practical value. The so-called identification, is to contain noise from the input and output data from the study was the data model. This data model is the process of input and output characteristics in a certain sense of approximation, while similar to the general accuracy of the data depends on the accuracy of sampling and identification method is reasonable.

wavelift
暂时只支持jpeg2000支持的 cdf97 和spline53
可以这样来测试:
x=imread( E:studyjpeg2000imageslena.tif )
% see the decomposition coefficients
y=wavelift(x, 1, spl53 ) using spline 5/3 wavelet
figure subplot(1,2,1) imshow(x) subplot(1,2,2) imshow(mat2gray(y))
% see the reconstruction precision
yy=wavelift(x, 5) using cdf 9/7 wavelet
ix=wavelift(yy,-5) inverse
sum(sum((double(x)-ix).^2))
(only temporary support jpeg2000 support cdf97 and spline53 this can be measured Examination : x = imread (E : study jpeg2000 images lena.tif)% see the d ecomposition coefficients wavelift y = (x, 1, spl53) using spline 5/3 wavelet figure subplot (1,2,1) imshow (x) subplot (1,2, 2) imshow (mat2gray (y))% see the reconstructi on precision wavelift yy = (x, 5) using cdf 9/7 wavelet ix = wavelift (yy.-5) inverse sum (sum ((double (x)- ix). ^ 2)

Multi2Carrier-Measurements
利用GNSS 进行高精度导航定位的前提是正确固定载波相位观测值的整周模糊度。由Galileo 系统的4 个载波观测值可以
形成诸多有良好特性的组合观测值,利用这些组合观测值,结合MCAR 方法,可以有效地确定整周模糊度。(The use of high-precision GNSS navigation and positioning the premise is correct carrier phase observations fixed integer ambiguity. May consist of four carriers observations Galileo system
There are many good characteristics to form a combination of observations using a combination of these observations, combined with MCAR method can effectively determine the integer ambiguity.)
