MATLAB is used to plot the uncompensated step response.
s = tf('s');
G = 4/(s^2+6*s+10);
figure;step(G);grid on;
It is observed that the settling time is 1.66 seconds. and peak overshoot is zero.
Now we need to design a compensator that settled in 1.66/2 = 0.83 seconds and maintains zero overshoot.
MATLAB code is given below for plotting the compensated step response.
code:
C = (0.91*(s+6.3891));
figure;step(feedback(C*G,1));grid on;
