Dimensions of matrices being concatenated are not consistent.

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

Show us the complete neat code which you tried.

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'})

That code does not give me errors in MATLAB Online
