(Tuis.) #1

In this model:


Create an slLinearizer interface for the model.


sllin = slLinearizer(mdl);


To obtain the plant model transfer function, use u as the input point and y as the output
point. To eliminate the effects of feedback, you must break the loop. You can break the
loop at u, e, or y. For this example, break the loop at u. Add these points to sllin.


addPoint(sllin,{'u','y'});


Obtain the plant model transfer function.


sys = getIOTransfer(sllin,'u','y','u');
tf(sys)


ans =


From input "u" to output "y":
1


s + 5


Continuous-time transfer function.


The second input argument specifies u as the input, while the fourth input argument
specifies u as a temporary loop opening.
