How to convert a set of transfer functions into state space model using MATLAB?

1 Ansicht (letzte 30 Tage)
Yb = -29.217; Yp = -0.258; Yr = 0.939;
g_1 = 32.17; Ydelr = 16.889; u0 = 456;
L_B = -6.73; L_P = -1.168; L_r = 0.245; L_delA = 12.903; L_delR = 1.069;
N_B = 5.6345; N_P = -0.0459; N_r = -0.2625; N_delA = -1.294; N_delR = -1.859;
Y_B = (Yb)/(u0);
Y_P = (Yp)/(u0);
Y_R = -1*(1-(Yr/u0));
g = g_1/u0;
Y_delR = (Ydelr/u0);
A_lat = [Y_B Y_P Y_R g;L_B L_P L_r 0;N_B N_P N_r 0; 0 1 0 0];
B_lat = [0 Y_delR;L_delA L_delR;N_delA N_delR;0 0];
syslat = ss(A_lat,B_lat,eye(4),zeros(4,2))
TF=tf(syslat)
TF(1,1)
TF(1,2)
TF(2,1)
TF(2,2)
TF(3,1)
TF(3,2)
These are the Transfer Functions obtained from a State-Space Model.
A=4 by 4 C=eye(4)
B=4 by 2 D=zero(4,2)
let's suppose, I want to formulate my own state-space model of dimensions stated above from 6 transfer functions embedded in a 3 by 2 Matrix. please help me out in this.
how can we obtain the same state space model using these transfer functions?
