Help. I need a pointer to the next step. 
I have a system that I need to control with a feedback loop.
I need to do a little bit more than stick a PID box in the
loop and push the "self-tune" button. I have the MatLab control
and system ID toolboxes, and can thus derive models for the
system. Problem is, I don't remember how to apply the information
from these tools to tune the system. Come to think of it, I don't
remember doing anything practical like this in school, but that
was long before tools like those above existed.
Are there any good books out there on the practical side of
control systems?
