I am looking for a simulation package to demonstrate control concepts
to a group of individuals without a control background.
I would like the package(s) to:
(1) use only one SISO loop for addressing simple issues, like
time constants, gain, tuning, etc. Simple level control
would be wonderful.
(2) Have a pair of SISO loops which exhibit steady-state coupling
and can use a decoupler.
(3) Be relatively inexpensive.
I have Tankspill and it is a good package. However, it has two
loops which display Dynamic coupling, but not steady-state. It
also may be a little complicated for objective (1) {remember,
these individuals have no control background.}
Please e-mail responses and I will post results.

The experiments involve a process furnace - christened the 'Purdue Furnace'! There are 2 outputs to be controlled: the outlet temperature of the process stream and the oxygen composition in the stack gas. There are 2 manipulated variables - the fuel oil flowrate and the air intake rate. Various control configurations can be implemented in the process. You can do both steady state and dynamic experiments, open or closed loop. I believe Purdue Chem E licenses this application. You can contact the School at 317 - 494 - 4075. Hope this information was useful.
