94 CHAPTER 3. FUNCTIONAL DESCRIPTION OF Xµ
Specify the outputs in terms of the subsystem names and the input names. Note that
individual outputs of MIMO systems and simple arithmetic combinations can be
specified. Parenthesis specify which output of a MIMO system is tobe used.
outputs = ["p(1) + wght"; "7.5*c";
"ref - 1.6*p(1) - 1.6*noise(2) - 1.6*wght"]
Now specify the inputs to each of the named subsystem. The order is important. Note
how the input to a multiple-input system (”c”) is specified.
conx = ["c";...
"ref-1.6*p(1)-1.6*noise(2)-1.6*wght; p(2)+noise(1)";...
"dist"]
Now the final system (clp) is formed.
clp = sysic(snames,inputs,outputs,conx,p,c,wght)
size(clp)?
ans (a row vector) = 3 4 4
rifd(clp)
