Hello, loading the ControlSystems Package using
<<ControlSystems` or Needs["ControlSystems`"]
Replys no error and
$Packages seem to contain everything I need (see attached out).
I tried the FAQ and found http://support.wolfram.com/mathematica/packages/loading/functionsnotworking.html
But it does not help me.
Names["ControlSystems`*"]
Out[]={TransferFunction}
In[61]:=
\!\(TransferFunction[s, 1\/s]\)

Out[61]=
\!\(TransferFunction[s, 1\/s]\)
Seems as if the function is unknown. But it is put in the correctNameSpace. S

In[62]:=
StateSpace[%]

Out[62]=
\!\(StateSpace[TransferFunction[s, 1\/s]]\)

StateSpace is put in the NameSpace Global.
Seems very strange. Needs["EE`"] and UsingBodePlot works fine.

Please send me every suggestion you have. Everything can help me. And I need it soon.

Yours,

Moritz
