MATLAB System Identification Toolbox three minutes to start

Matlab, with a lot of toolbox, because the curriculum requirements to use the System Identification Toolbox, that is, systems identification toolbox
Oneself toss for a while, be kind of reluctantly will use, here simple explain how to use
Very simple ... We can start in three minutes.
The Prime minister in the work space to identify the data you want to import, will not import the words themselves find a matlab book turn it Over
Open System Identification Toolbox Only one Exit button is available, crazy halo ...
First point Import Data Drop-down menu, you can select the time domain or frequency domain, according to their own needs to choose, and here I choose the time domain will pop up an import Data dialog box, there is a workspace variables, fill in here you just imported data variable name
The following is the data information is the name, no use, write a favorite you like, or simply do not tube, starting time start, sampling interval sampling cycle, fill in the demand
All filled out to choose import on it. At this time in the Import data Drop-down menu, there is a working data, and then select the Preprocess is the data preprocessing, attention to the pretreatment of the object is the data in working, Each preprocessing in the left two columns will have a new data generation, then as long as the new data drag, moved to the box of working data, you can change the working data you want to deal with, you can do so many times, Get the data you eventually want to identify and the data to use for validation (unwanted data can be dragged into that trash, either the Recycle Bin or retrieved from the Recycle Bin), and the next step is to identify, and first drag the data from the identification to the box in working. And then drag the validated data to the validation box.
Click the drop down menu estimate, choose the model you want, in the pop-up dialog box to set the parameters after the point estimate, there are models generated, in the right data bar, that is, the model views, there are a lot of options, each one can generate a corresponding map, is generated by the data used for validation.
can only see, but can not know the parameters of the model is how much ...
The same way to drag the model to the box to workspace, and then to see the workspace, the more variable is the model you identified
Views have a lot of settings, one try to know, in a model or a group of data on the point, the line will be thinner will not be shown in the figure
That's the whole thing, and one of the rest is easy to try.
