figure(2),step(tf_cl),grid on % step response of the close-loop system
f3db_ol = bandwidth(tf_cl) % calculate the close-loop bandwidth
figure(3),bode(tf_cl),grid on % bode plot of the close-loop system
figure(4),bode(tf_ol),grid on % bode plot of the open-loop system
f0dB_ol = getGainCrossover(tf_ol,1) % calculate the unity gain frequency (crossover frequency) of the loop gain
figure(5), margin(tf_ol),grid on  % calculate the phase margin and gain margin of the loop gain
figure(6),pzplot(tf_ol)  % pole and zero plots of the loop gain
