Hello, I have a state space model as:
A =
x1 x2
x1 -266.7 400
x2 -400 -266.7
B =
u1 u2
x1 333.3 0
x2 -2848 -2515
C =
x1 x2
y1 1 0
y2 0 1
D =
u1 u2
y1 0 0
y2 0 0
This model needs to be put as an input to a LPV block. but when I so, it gives me this error
"Dimensions of matrices being concatenated are not consistent."
Some help would be great.
Thanks

Sure. The script is as:
R = 0.8;
Ld = 3e-3;
Lq = 3e-3;
L = Ld;
J = 0.000235;
Bdamp = 0;
lamda = 85.45e-3;
p = 4;
wm = 100;
w_s = tf(89,[1,0.17]);
w_t = tf(0.002,[1,0.002]);
Ts = 0.4;
A = [ -R/L p*wm; -p*wm -R/L ]
Bp = [ 1/L 0; 0 1/L ]
Bfw = [ 0 ; -wm*lamda/L ]
C = [ 1 0 ; 0 1 ]
D = [zeros(2,2)];
B = Bp + Bfw
sys = ss(A,B,C,D,Ts,'InputName',{'vd','vq'},'OutputName','y','StateName',{'id','iq'})
