My name is Martin Kanner (an old time controls engineer) and I have been mentoring for team 353 for 6 years. I marveled at the technology of the PID but I coudln't see how it could be applied in an engineering fashion with the information available. My basic point is that a closed loop is designed for performance and stability. This is not to be accomplished by trial and erorr. My experience has been with the application of Bode analysis and Bode plots. I have completed 3 files so far entitled "The PID Revisited". I expect to complete two more files to be complete. I believe they contain the basics for designing closed loops. If anyone is interested, I'll e-mail PID11, PID22 and
PID33. They are pretty short but I believe contain some simple but important fundamentals. My e-mail is,
