Create an slLinearizer interface for the model.


sllin = slLinearizer(mdl);


To obtain the loop transfer function at e, add this point to sllin as an analysis point.


addPoint(sllin,'e');


Obtain the loop transfer function at e.


sys = getLoopTransfer(sllin,'e');
tf(sys)


ans =


From input "e" to output "e":
-3


s + 5


Continuous-time transfer function.


The software adds a linearization output, breaks the loop, and adds a linearization input,
de, at e.


sys is the transfer function from de to e. Because the software assumes positive-
feedback, it returns sys as.
