MATLAB: State space to transfer function conversion

control systemsstate-space

   dx/dt = A x+  B q +  E u
   y  = C x+ D q  +  F u
the above is a state space representation of my model
where x -states
       u-input
       q- disturbance /load
A,B,C,D,E,F corresponding coefficient matrices
how to convert this state space representation to transfer function

Best Answer

Your system can be written as
dx=C.x+B1.e       % With e=[q;u] and B1=[B E]
y=C.x+D1.e        % With D1=[D F]
Then Use ss2tf as usually.
