Query Value of Multiple Tunable Elements within Custom Parameterization

Create an slTuner interface for the scdcascade model.

open_system('scdcascade');

st = slTuner('scdcascade',{'C1','C2'});

Set a custom parameterization for one of the tunable blocks.

C1CustParam = realp('Kp',1) + tf(1,[1 0]) * realp('Ki',1);

setBlockParam(st,'C1',C1CustParam);

These commands set the parameterization of the C1 controller block to a generalized

state-space (genss) model containing tunable parameters Kp and Ki.

Typically, you would use a tuning command such as systune to tune the values of the

parameters in the custom parameterization.

After tuning, use getTunedValue to query the tuned values of both Kp and Ki.

[KiTuned,KpTuned] = getTunedValue(st,'Ki','Kp')

KiTuned =
