Error in port widths or dimensions of multiple mpc

A1 = [0, 1, 0, 0;

-m*g*L/j, -1000/dsitadx/j, s1/dsitadx/j -s2/dsitadx/j;

B1 = [0; 0; 27497334708.4608; -42904277761.8731];

C1 = eye(4);

D1 = [0; 0; 0; 0];

Error in port widths or dimensions. The signal connected to the "mo" port of the "data_4_17/Multiple MPC Controllers/MPC4" block must be a scalar signal.

Error in port widths or dimensions. The signal connected to the "mo" port of the "data_4_17/Multiple MPC Controllers/MPC1" block must be a row or column vector signal with 4 elements.

I don't know how to solve the problem.

Of course, mo will be 4*1.But why does this happen?

Hi @曜星,

For better understanding of your issue, it will be great if you can share the model.
