Analyze Outer-Loop Sensitivity at Plant Output

To obtain the outer-loop sensitivity at the plant output, use y1 as the analysis point. Add

y1 as an analysis point to sllin.

addPoint(sllin,'y1');

Obtain the outer-loop sensitivity at y1.

So = getSensitivity(sllin,'y1');

Plot the step response of So.
