Salwa Ben Ammou(2010) set out a hybrid data analysis method based on the combination of wavelet techniques and principal-components regression.
There are two type of wavelet transforms namely continues wavelet transform (CWT) and discrete wavelet transform (DWT) according to the length of data.
After trained by the historical data of a time series the network can capture the non-linear characteristics of the time series and make forecasting the time series in future according to a given precision.
Empirical results The sample data sets are daily SSE Composite Index at the close from 01/01 2010 to 11/31 2012 which are obtained from the Shanghai Stock Exchange (SSE).The training data started on 01/01 2010 and ended on 06/30 2012, and the testing data started from 07/01 2012 and ended to 11/31 2012.

By sampling the sample data trains this neural network for certain steps to achieve error precision, that is the desires of inverse system,which is concatenated ahead of the induction motor speed-controlled system, making a pseudo linear system.
The input given choice covers the whole motor work area, make sure the system can get affluent enough training data.
At the same time, the sampled data should experience the secondary filter for to reduce the errors between measured value and true value
(2) The first step is to deal with the sampling data, and processed data is set as training sample.
In order to accelerate the convergence of neural network training, the first thing is to make input and output sample data of training are normalized

The useful data used for alignment is seriously polluted by harmful base angular motion formed in external perturbation, and it leads to the reduction of systematic reaction speed and precision of navigation.
So it needs to a data preprocess.
The data and frequency spectrum of FOG output shows in Fig. 1, and those of filter data are in Fig. 2.
Then it needs to reject this data and sample again, there we replace it with a random data of previous period, for the real-time character of the procedure.
The data after detection is as Fig. 5.

As a consequence, the experimental values of DHI and theoretical data on DEI are also well comparable.
As DHI0 is independent of temperature, this quantity could be good candidate for comparison to theoretical data.
Solid triangles: experimental data (AES, FIM, 3D APT); empty triangles and/or dashed line: (experimental) prediction; dotted lines: extent of the error of the values determined experimentally; solid circles: DFT values; solid squares: other theoretical data (MS, TB).
A possible explanation might consist in the used type of relaxations in the DFT data.
Other symbols including the reversed triangles are literature data for polycrystalline a-Fe [4,8].
