"Poor man's" regulacija lemilice 24V

"Da li se iz ove naše šeme (sa prve strane) može nekako odrediti koji parametar utiče na to koliko će grejač raditi "u komadu" pre nego što počne da "svićka"? (Meni se čini da prerano ulazi u taj "svićka"- mod Smile tj. predaleko od zadate temperature...)"
----------------------------------------------------

Pazi, malo je slozeniji odgovor na to pitanje nego sto na prvi pogled izgleda.
Morao bi da poznajes teoriju koja stoji iza toga jer ne mozes da menjas nasumice te vrednosti + paramtri su medjusobno zavistni, recimo ti krenes da menjas jedan parametar (komponentu) to ce uticati na drugi parametar i tako bi se vrteo u krug.
Postoje tacne metode kako se to radi, recimo jedna je Ziegler–Nichols a vise o tome mozes procitati ovde:

https://en.wikipedia.org/wiki/Ziegler–Nichols_method
https://en.wikipedia.org/wiki/PID_controller
Za to bi ti trebalo da imas nekako logovanje temperature i iscrtavanje grafikona …
Sama metoda je relativno slozena i zahteva vise iteracija tokom stelovanja.
Druga varijanta je preko step-response ali i za to ti treba logovanje temperature …

Kada stelujemo PID za neke druge namene (npr u AMP-ovima), situacija je nesto jednostavnija jer se barata dosta brzim procesima (dosta cu kraca vremena) i to je onda moguce pratiti preko osciloskopa uz pomoc nekih signal generatora; u srzi nema razlike da li odrzavamo temperaturu, napon, struju, brzinu … sve je to jedan isti PID algoritam ...
