[Scilab-users] Problems with Bode and Bode asymptotic

[Rafael Guerra]

Hello,



Noting that bode_asymp() takes (rad/s) inputs and that the bracketed syntax [ , ] in Scilab's help file means optional inputs, please check this:



// START OF CODE

xdel(winsid());

fmin = 1e-2;

fmax = 1e4;

wmin = 2*%pi*fmin;

wmax = 2*%pi*fmax;



f1 = 100;

w1 = 2*%pi*f1;

tau1 = 1/w1;

H1 = 10/(1 + tau1*%s); // order 1 system

S1 = syslin('c',H1);

scf(1);

bode(S1,fmin,fmax);

bode_asymp(S1,wmin,wmax);

xtitle('Order one');



m = .125;//sqrt(2)/4;

wn = w1;

H2 = 10/(1 + 2*m*%s/wn + %s^2/wn^2); // order 2 system

S2 = syslin('c',H2);

scf(2);

bode(S2,fmin,fmax);  //

bode_asymp(S2,wmin,wmax);

xtitle('Order two');



scf(3);

bode(S1,fmin,fmax);

// END OF CODE



Regards,

Rafael
