Algorithms for automatic PID tuning?

Question

I am given to understand that there exists software for tuning PID controllers. I haven't had much luck finding references, though. Pros/cons for algorithms, and references for them?

ADDED: I'm specifically looking for a description (scholarly or otherwise) of how automatic tuning software does its job; not references to automatic tuning software or packages. My use case is not "I have a PID control loop I want to automatically tune" but rather, "I wish to write a piece of software to automatically tune PID control loops for particular pieces of hardware, so that others do not have to do the job manually."

The reference states that this is often implemented in hardware. Are there any chips that incorporate PID tuning? — JonnyBoats, Dec 31 '11 at 05:22

This paper discusses a method for automatic tuning, that at least this company seems to use for their automatic online self-tuning controller.

Matlab (expensive) and Scilab (free) offer PID modeling and can be used for tuning PID control systems. Here is an example using Scilab.
