sys is the transfer function from du to y, which is equal to.

Obtain Open-Loop Response Transfer Function for Specific Parameter

Combination

Suppose you batch linearize the scdcascade model for multiple transfer functions. For

most linearizations, you vary the proportional (Kp2) and integral gain (Ki2) of the C2

controller in the 10% range. For this example, calculate the open-loop response transfer

function for the inner loop, from e2 to y2, for the maximum value of Kp2 and Ki2.

Open the scdcascade model.

mdl = 'scdcascade';

open_system(mdl);
