Using Ha mmerstein-Wiener Plots to Validate Models

• To plot u

as a command of the input data, click the u

block.

• To plot y

as a comm and of its inputs, click the y

block.

The selected block is highlighted in green.

Note An input to the output nonlinearity block y

is the output from the

Linear Block and not the measured input data.

3 If your model contains multiple variables, select the channel in the Select

nonlinearity at channel list. Selecting the channel updates the plot

and displays the nonlinearity values versus the corresponding input to

this nonlinear block.

4 To change the range of the horizontal axis, select Options > Set input

range to open the Range for Input to Nonlinearity dialog box. Enter the

range u sing the format

[MinValue Max Valu e].ClickApply and then

Close to update the plot.

Plotting Linear Block Characteristics

The Hamm erstein-W iene r model contains one Linear Block that represents

the e mbedde d linear model.

To conﬁgure the p lo t:

1 If the top pane is not visible, click to expand the Hammerstein-Wiener

Model Plot window.

2 Click the Linear Block to select it. The Linear Block is highlighted in green.

3 In the Select I/O pair list, select the input and output data pair for which

to view the response.

4 In the Choose plot type list, select the linear plot from the following

options:

•
