How to paint a bode picture with open-loop transfer function G(s)=5*(0.0167s+1)/[s*(0.03s+1)*(0.0025s+1)*(0.001s+1)] in matlab

open-loop transfer function:

G(s)=5*(0.0167s+1)/[s*(0.03s+1)(0.0025s+1)(0.001s+1)]

bode picture in matlab

>Solution :

num=5*[0.0167,1];

den=conv(conv([1,0],[0.03,1]),conv([0.0025,1],[0.001,1]));

G=tf(num,den);

w=logsapce(0,4,50);

bode(G,w);grid;

[Gm,Pm,Wcg,Wcp]=margin(G)
