RST controller: Looking for a tutorial

Hello,
I was wondering if any of you guys happen to know where I can find a good tutorial on RST controllers?
I looked in a book I have about PID controllers, but the book
didn't mention anything about RST controllers. So I am also wondering if RST is just another name for PID controllers?
Thank you,
John
