Algebraic ss2tf

ss2tf function for algebraic state space equations

alss2tf function creating transfer function from algebraic state space equations

Ex:

syms a b c d e f g h i;
A=[a b c; d e f; g h i];
B=[0; 0; 1];
C=[8 9 0];
D=0;

[TF_Num,TF_Den] = alss2tf(A,B,C,D)

Result:

TF_Num =

9*a*f - 9*c*d - 8*b*f + 8*c*e - 8*c*s - 9*f*s


TF_Den =

a*s^2 + e*s^2 + i*s^2 - s^3 + a*e*i - a*f*h - b*d*i + b*f*g + c*d*h - c*e*g - a*e*s + b*d*s - a*i*s + c*g*s - e*i*s + f*h*s
