Funny, I always though it was the other way around. The Z-N methods were ment for guys that didn't understand control theory. The cookbook method was a way a plant manager could get his plant under control if he was unable to model the dynamics and apply control theory. The PID is a similar device.
Anyway, I took a look at your video and code. You did a great job and I wish our team had the capability. We are using C++ and I have longed for that data/plotting capability to tune the PID loops. I know teams like 254 have used a similar data loging scheme that reads the data bus and plots it using a custom LV GUI. Have you done any of this with C++ or can you offer some suggestions on the best way to set PID constants on the DS , send them to the robot and retrieve the sensor data and display it.
