Question

SIMULINK

the first function is already simplified and located in the block:

Functioni: K*wn^2 $2+2*zhita*wns G1(s) = K * wn2 S*(S + 2 * zhita * wn) Transfer Fcn4

NOw,I have problem with function # 2,I need help to properly put function # 2 in the simulink "trnafer fcn5 'block, ... I cannot add the letter' s' in neither the numerator nor the denominator, because since I already have a script code, it only calls the matlab.m file.That is why '0' or '1' is used in this case to call the code 's' variable. m

if I click on the block, it opens to edit the numerator and denominator, which should be put there so that it looks like the 'G2(s)' function which is the original ... remember that you cannot put the letter 's'

my question is what should I put in the numerator and denominator so that it remains as the given function G2 (s)

Answer 1

Consider the transfer function (s). +1 ]w S K +1 wn? wa G(s)= s(s+2 * chita* wn) +1 wa S Re-arrange the equation as follows: Ks - wn? + Kwn wa G(S) = +2* chita* wn*s)* +1 wa KS wn- + Kwn wa si 252 *-hita* wn +(s2 +2* chita*wn*s wa K -wns +(Kwn) wa G(S)= 1 2* chita* wn +1 52 +(2* chita* wn)s wa + wa 3 + wa

In Simulink block, need to give the following values: Numerator coefficient: [(K/wa)*wn 2 K* wn^2] Denominator coefficient: [(1/wa) (2*zhita*wn/wa)+1) (2*zhita*wn) 0]
