PIDemystified! A tutorial covering the NEW PID logic of Artisan 3.4

Описание: This is a DEEP DIVE into the world of PID as it pertains to coffee roasting using the amazing open-source Artisan software! Yes, it's long, but it's broken into chapters so that you can digest this in smaller parts.
The chapter points below can help you jump to the right chapter:
00:00 Introduction
02:10 Generic PID terms
03:22 New PID Graphing features in Artisan 3.4!
07:14 Understanding the P term: Proportional
10:35 Fahrenheit vs. Celsius - It matters!
12:06 The diminishing impact of P
14:08 Understanding the D term: Derivative
17:48 Understanding the I term: Integral
28:04 Error is Important (ESSENTIAL, in fact!)
29:40 Approach the background SLOWLY
33:11 Addressing the "crash and flick"
37:10 Setting multiple PID values for one roast
41:00 New advanced PID settings in Artisan 3.4
45:07 Nearly 2 hours of consecutive roasts in 75 seconds :-)

Artisan 3.4 completely re-wrote the PID algorithm used for automating the heat control of coffee roasts, and when properly understood and implemented, it can show a BIG improvement in tracking... especially at the troublesome "crash and flick" after first crack!
None of this functionality would be possible without the tremendous efforts of Dr. Marko Luther and the Artisan team, so please consider supporting that project by utilizing the Artisan Plus inventory management system, or by donating directly to Artisan at https://artisan-scope.org/donate/
