Also plot the deflection and the respective contributions of the feedforward and
feedback paths:
T = getIOTransfer(ST,'Nzc','delta_m'); % transfer Nzc -> delta_m
Kf = getBlockValue(ST,'Kf'); % tuned value of Kf
Tff = Fro*Kf; % feedforward contribution to delta_m
step(T,'b',Tff,'g--',T-Tff,'r-.',6), grid
ylabel('\delta_m'), legend('Total','Feedforward','Feedback')
Finally, check the roll-off and stability margin requirements by computing the open-loop
response at.
