The step response for all models varies in the 10% range and the settling time is less than
1.5 seconds.
Analyze Inner-Loop Transfer Function at the Plant Output
Obtain the inner-loop transfer function at y2, with the outer loop open at e1.
Li = getLoopTransfer(sllin,'y2',-1);
Because the software assumes positive feedback by default and scdcascade uses
negative feedback, specify the feedback sign using the third input argument. Now,
. The getLoopTransfer command returns an array of state-space (ss)
models, one for each entry in the parameter grid. The SamplingGrid property of Li
matches the parameter values with the corresponding ss model.
