Simulink Control Design™ - MathWorks

You can change the model after your first call to getIOTransfer, getLoopTransfer,

getSensitivity, or getCompSensitivity with sllin. Some changes impact the

linearization, such as changing parameter values. If your change impacts the

linearization, call refresh to get expected linearization results. For this example, change

the proportional gain of the C2 PID controller block.

set_param('scdcascade/C2','P','10')

Trigger the interface to recompile the model for the next call to getIOTransfer,

getLoopTransfer, getSensitivity, or getCompSensitivity.

refresh(sllin);

Resynchronize slTuner Interface with Current Model State

Create an slTuner interface.

st = slTuner('scdcascade','C2');

Generally, you configure the interface with analysis points, openings, operating points,

and parameter values. Then, you tune the model block parameters using the systune

and looptune commands. You can also analyze various transfer functions in the model

using commands such as getIOTransfer and getLoopTransfer. The first time you call

one of these commands with st, the software stores the state of the model in st and uses

it to compute the linearization.

You can change the model after your first call to one of these commands. Some changes

impact the linearization, such as changing parameter values. If your change impacts the

linearization, call refresh to get expected linearization results. For this example, change

the proportional gain of the C1 PID controller block.

set_param('scdcascade/C1','P','10')

Trigger the interface to recompile the model for the next call to commands such as

getIOTransfer, getLoopTransfer, or systune.

refresh(st);
