Looks pretty good.How do the hold times compare? They are a little hard to read on my laptop.
Is Ki zero?
Is the green line output?
...Very nice profile control! It's matches my default profile that I set up at work for un-profiled boards. Works great for all but two of our boards. One is very thin and the other is a 16 layer board with mulitple ground planes. They require special profiles.How do you profile your boards if you need to?
It looks like you have too much thermal mass for your size of heater since there is substantial lag even with the heater fully on.. And you need a method of cooling that mass when ramping down - say a fan blowing ambient air.
You also need a bit more integral action as evident by the "controlled" deviation at the high temperature. Integral action is designed to reduce off-set error based upon how long the error exists. It is evident that you are still applying heat even with the deviation existing.
